If your version of GD supports GIFs (which not all do), then it's almost as
simple as changing every place you see the string "jpeg" to "gif".
Look in the online manual for the image functions. You'll see reference to
the ones here (such as imagecreatfromjpeg()) and also ones for PNGs and GIFs
and a few others.
Just realize that when you are reading a file of a particular type, you need
to use those image<type>() functions... But in most cases they are
completely interchangable if you're passing paths to images of the
appropriate type.
Hope all of that makes sense :)
