Super AJAX Programming Seed is a tight little program that illustrates a simple implementation of AJAX technology using HTML and PHP, and offers suggestions for how to use the technology to make super-dynamic web applications from scratch. It's a lot of fun, and after seeing how simple it is you'll never stop coming up with new ways to use it.

Image Resize Wizard is a free program that takes two inputs - an image URL and the size - and creates code to generate a new, re-sized image on-the-fly. You can add the program to your web site or use it yourself and it's super easy to install.

Copyright It! is a tool that allows you to add copyright notices directly onto your images without any fussing around in image editors. You can either use the program yourself, or add it to your web sites to add functionality. The program lets you enter the copyright text, the font size, and the color of the notice. The program also uses a unique temporary file system, so your server doesn't get overloaded with files.
