Image Comparer 3.0 was available as a giveaway on October 11, 2007!

Today Giveaway of the Day
free today
Complete, reliable and fast Windows PC backup software for personal use!

Image Comparer analyzes your digital images and automatically selects the best shot out of the many duplicates, allowing you to move or delete duplicate images in a couple of mouse clicks. Image Comparer uses content based image search also known as content based image retrieval.

Unlike similar products, Image Comparer does not just look for exact duplicates. Instead, it analyzes and recognizes an image's content, and groups pictures that look alike. You can specify the level of visual similarity that is sufficient to consider pictures to be duplicates. View them in pairs or see the top ten similar images and keep the best one!

Image Comparer is extremely useful to professional photographers, designers, and webmasters, who have "image-heavy" sites to maintain. The program is incredibly fast; after a minute or two one can see how many duplicate images are stored and how much disk space will be saved by removing the duplicates. The "dupes" can then be removed all at once with one click. Alternatively, a user can specify which images need to be deleted, moved or copied.

The list of supported image file formats includes RAW, JPEG, J2K, BMP, GIF, PNG, TIFF, TGA and other.

Useless in W98se despite claims otherwise.

When launching IC 3.0 and wishing to create gallery, the only oprion offered was for .icg files (Image Comparer Gallery files). Now, what good is that, if one has not been able to create any gallery to begin with ?

Next, I used this GAOTD image Comparer 3.o to check for updates. It did; successfully. It downloaded updated 3.1 which displayed "W98 compatibilty fixed". YAY !And that does work for W98se with one major problem. It is trial. The previous GAOTD activation key won't work.

Now, I understand that these GAOTD products cannot update or offer support. That's fine, but at least the thing should work. Inasmuch as it doesn't as there's a bug in the release -until one does update - what the heck good is it ?

I rate it *ZERO*. Useless.... Bah!

Neither did i ever use or install a debugger, nor do i know what that is.
Going for another tool

"IM0062.jpg to Clear Lake.jpg"
i prefer:
IM0062.jpg to ClearLake0062.jpg. Occas that same number 0062 shows in another filename, but it's easy to spot those files as different.

to all: try doublekiller. fw. fast. compare includes crc ( a kind of checksum). a few conveniences (when changing directories) and inconveniences (would be nice to somehow view, even including the win context/shell menu in DK's context menu would be good)
I found my self opening both folders to rename and slightly reorganize my folders. so it's a reorg tool for me.

i haven't used i much, but after some checking, it seemed to make no errors. however DK is a pure dupe finder; DK is not trying the semi-utopian "find me the best version of similar images" task.

I don't get how anyone can find DupDetector to be better than Image Comparer except maybe for ease of use. Especially if DupDetector requires the pictures to be in the same folder - that just seems meaningless. Some of the other tips might be worth checking out, but for my use Image Comparer does the job just fine.

Steve (#35) look on softpedia for imagediff, it shows the differences added by filters, etc. freeware.

Not exactly freeware, but not too spendy if one is broke, either- anyone try PictureRelate? worth a shote, eh?

personally what I need the most is to find different pixel sizes of the same image, so this may work fine. take a while lining up candidates....

encountered a problem and must exit. Anyone have a simular problem or a fix. loaded it twice and got the same issue.

I downloaded this program and ran it against all of my vacation pictures from a cruise I took two years ago. Then I went through to see how good a job it did. There were some cases where it was dead on. For instance, two very similar pictures of the same ship showed up with 95 percent accuracy. But more often, it would say that there were pictures that matched that were nowhere near the same thing. For instance, one picture I have of the ship we were on had three matches with 95 percent or greater. All three of these were pictures of cliffs and other rock formations. Definitely not even close to the ship.

So while it did work pretty well in some cases, it totally missed the boat (haha, couldn't resist) in many other cases. Interesting idea though.

if you edit pics a lot i guess there is a 0.000002% chance of being a little bit useful, but its probably better to look at a picture with yoru eye than having a computer program compare each pixel or set of pixels that make up a picture. I guess someone was just trying out a new algorithm or something, but not worth the cost in my opinion.

Thanks for those who told about Dup Detector. I know we 'suppose' to try today giveaway and give comments. But after reading all the comments,(which not too 'attracting') I don't think I want to 'risk' it cos my pc crash before (I don't mean Image Comparer will cause this. sry) So need a handy tool to help.
Thanks GOTD as I won't get to 'know' so many of other valuable alternatives from the readers, if I didn't know about your site. :) God bless you guys. Have a wonderful day.

This is very special day for me. Today I bought a license copy of Windows XP Professional and I'm not longer a "pirate".
On the second hand, this is very special day for me because few days ago I translated the interface of Image Comparer into my native language and I obtained a licensed copy of this USEFUL program. Yes, this is the right word- "USEFUL". And I'm very glad that this program is on GAOTD today.

Why the #$%&* does this program not allow me to drop a folder on it? Each and every time starting out with such a clumsy winzz folder tree from the bottom - my computer etc.- annoys me.

The app can not handle big numbers. No way of loading 15,000 pics.

If you have less than 100 photos, doing it by eye is better. I would assume that it allows you to delete the image you do not need, rather than doing it, itself (that would be really dumb software). DupDetector needs all images on one folder, whilst mine are across 3 different hard drives (I have lots of pictures). So will give this a buzz after seeing BladedThoth review.

Reply   |   Comment by Clive  –  16 years ago  –  Did you find this comment useful? yes | no (0)

The disadvantage of this software is that it is so very unintuitive. One would expect 2 images next to each other to compare and see with your own eyes if the software was right and then choose which one to remove. 'Dup Detector', as mentioned in one of the earlier comments, does exactly that. I could immediately see what to do.

But with this Image Comparer, I was at a loss on what to do. I'd chosen a folder, let it check all images... and then left me with a huge list of files that supposedly were my images, and then what? No hints or whatsoever on what to do from that point on. It's too unclear in its actions that I'd actually recommend not to bother with this and try out Dup Detector instead.

Reply   |   Comment by Trinsec  –  16 years ago  –  Did you find this comment useful? yes | no (0)

This produces the weirdest results I have ever seen. For instance, it takes a beige background jpg and says it is 93% the same as a jpg image of a black and white purchase receipt! Let's face it, there is absolutely no correlation between the two images. That was just one example among many. Yes, it did find some that were identical, but they were Photoshop files and the jpg files made from them; not exactly the duplicates I was looking for. Oh well.

I might also mention that I did not get the layout shown in the tutorial posted here when I opened the program, even after bypassing the wizard. So far, the program has been most unhelpful. >>

Reply   |   Comment by Jahala  –  16 years ago  –  Did you find this comment useful? yes | no (0)

I personally have used "DupDetector" (free) for nearly 10 years. I don't use it too often, but it has proved itself surprisingly accurate, if set for 95%. I've used it on thousands of pictures and it finds pictures the same, or taken from a slight difference in angles (your choice, depending on what percentage of similarity you set it to search for). To my surprize, it ignores the file's names, but goes on only the content of the pictures - It even CORRECTLY IDENTIFIED as the same; one picture that had been enlaged and then cropped to remove most of the background. That really did impress me.

ONLY the same/similar photos are then listed (side by side) in the results window, so you compair them and make the ultimate decision which you want to delete/move/etc.


I have never tried the Visipics mentioned here, but will also give that a try in the sake of fairness. I found it on:

I keep seeing comments from folks that are trying to equate the quality of a program with its price tag. Some of the best (usefully)programs I have on my hard drive I downloaded without any cost to me. They are for very specific uses and they probably would produce little or no income for the developer - mainly because they would be of little use to most people that live outside of my favorite hobby. Because they have a narrow appeal, I suppose that the cost of marketing them could exceed the amount that their sale might produce. Their low cost, if there is any charge for them at all, is not at all indicative of their quality.

The programs that I am referring to are developed and circulated by amateur radio operators with high interest levels for their hobby. The programmer gets some recognition when the programs are of high quality but the recognition does not take the form of income.

For the most part, the programs on this site are not free. Some of these not free programs seem to be nicely done. As I see it, a program can have limited appeal and a low cost and still remain a high quality effort.

I am very pleased with this gift. The last period of time i categorized my 5000 pics with keywords(a lot of work). Now i can test if my memory is better then this software. Conclusion, this software beats me. If you have stored your pics in more then one dir, you can't find all the duplicates. This program is very usefull. A couple of hundreds duplicates it did find.

Reply   |   Comment by Dirk  –  16 years ago  –  Did you find this comment useful? yes | no (0)

Small problems with multiple monitor compatibility.

When tested on my web development directories, this was fairly fast. It takes a bit of tweaking to get it to do what one wants, buit it was not too hard. None of the pics was much over a MB.

However, when tested on the same test directory of 175 photos of a wide range of photo sizes (the one that I used on Express Thumbnail Creator two days ago).

The small format photographs are 5792 X 7557 and come in at around 129 MB, and medium format is 9584 X 11808 producing files that are 332 MB. The large format pics are 13376 X 16059 and weigh in at over 600 MB.

Compared with small format pics, the program slows noticably on the 129 MB files, stalls on the medium format 332 MB files, and stalled completely on the 600 MB photos. I do mean stall, as disk activity stopped completely and CPU useage dropped to zero for this program (thus, clearly it was not doing anything), and after a few seconds, Task Manager marked the program as unresponsive.

Good for amateur photogs, web developers, the eBay crowd and other amateurs with lots of small format photos. Not something a modern pro would use.

Amateur photogs, this program is worth trying out since it is being offered for free. I can't imagine that anyone who knows anything about photography would be paying the retail price. This is one of those programs most valuable for free, and will probably make some retail sales to the ignorant and uninformed who spot it on the shelf as an impulse purchase. But the majority of retail sales will be made when Best Buy or CompUSA puts it in that little clearance bin next to the cash registers and sell it for under $5.

Pass. There's no way I'd let any kind of computer-based decision select a "best" picture out of a group. I appreciate the offer, but there's just no way.

#19: This app compares the image, not the file. It's not saying the .psd and the .png are identical files, it's claiming it contains the same picture. I do however agree that the "100%" is not always accurate, as I expect 100% to mean identical, not "similar". Still, I found this feature very helpful going through a large database of thousands of pictures.

#22: Image Comparer doesn't deletes photos without your permission either. And if you don't want it to "screw up" some of your sets you simply don't include the folders in the comparison. Did you even try the program?

I've used this software before, and I find it very useful. I'm going to install this giveaway on my home PC as soon as I get home.

Does this software allow you to a "diff" of images? That's what I'm looking for. Not just comparing, but picking two images, selecting "diff" and seeing exactly what is different between the two of them.

I found it very useful. I have a couple thousand photos and no way can my brain see all the dupes. I have learned over time to use a similar file name instead of changing IM0062.jpg to Clear Lake.jpg

It installed fine on XP, took 2.5 min to load my photos and another couple to compare. I found those it rated 99% were almost always dupes. At 98 it got iffy and at 97 few were. The feature telling you which of the 2 is the better photo is interesting. I wish it told me how much storage I gained. It also gives you option to move checked dupes.

You go through and check mark which of the dupes to delete.

Downloaded, installed fine. But to be honest, I really don't see what use this program is to anyone. I mean, if you want to see which photo's are similar, why not just look at your pics? ... alot easier, and saves you hard drive space =].

And the fact that "there's no help yet" presents a problem. Thanks GOTD, but I will uninstall and pass on this one ... you see I have the power of the human eye ^_^. Although that "All my software" app sounds good :P *hint* *hint* haha :P

i just turned the Image Comparer 3.0 on to a jpg file of 6500 pix with good results. it found 1535 exact matches after twenty minutes.
Anything less than exact match is questionable at best.it compared different pix at 99% match. At lower % it presented a black background and a white background as a match.
i`m going now to check the tutorial to learn more of the controls.

right now i can only give a fair rating.

This is not something I would use on my personel photos, due to possible loss. you could easily delete family photos from different events because of similarities in scenes.

This appears to be good for web mining, as seen by the selection of photos in the tutorial. In other words looks great for sorting best photo of interest from web page raiding.

still for that purpose should be great.

XP Pro SP2 - Installed fine. Found it would not run against the root directory. Comparision was very good, better than previous apps tried. Pictures taken at basket ball game found simularities where it was the same court shot but players in differnt positions, very useful for grouping shots. Will be usefull on my home system where I have over 3 dvd's worth of pictures.

Installed in seconds.
Took 85 seconds to load up 4798 images into a Group to compare.
Took 5.5 minutes to compare images in group. (I have a couple gigs of ram, also)

Have to visually check names and images against each other, because it called some of my .psd images a 100% duplicate of some .png and .bmp files it compared them to !! :(
(a .psd is NOT a .png nor a .bmp etc. so the 100% duplicate comparison is a bit flawed.)

It took me over 10 minutes to manually choose which of the 987 "100% Duplicate" to delete.

Now that I've scanned my entire image folder, it's time to uninstall this app. I could have scanned for duplicate files with other freeware (that doesn't call a .psd a .png, etc.)

Fun little exercise for the morning, though. My hard drive is a little cleaner, I guess.
