I found a script for displaying photos and making categories, but even after editing it I cannot get it to do everything I want. The biggest problem is that it only displays JPEG files, how do I get it to show PNG and GIF as well? Also, it uses the folders in my directory to create categories, but I do not know how to allow the user to select which category it goes in. How do I do that?

This line is your problem. It’s specifically looking for a JPEG.

This will force GD to determine the type of image from the file’s contents.
