I've done one transparent overlay of two pictures, too, but found it a
bit tricky to do.
You have to be careful with using imagecopymerge. As i remember there is
a parameter to allow transparency to be used.
I wonder if different imagetypes can be used without any probs? Please
tell if you have tested it, i'm curious about it.
