I'm wondering why there doesn't seem to be any PNG support for the image list object, and I think it should definitely be in there. Unless it's a bug, and the image list DOES support PNG files. Here's a test demonstrating it in case it's a bug: Image List.
It's not a bug, there's no builtin Windows support for loading images other than BMP .

All of my hopes and dreams... shattered.
You could always use Image Manipulator to convert the image to a BMP, if you have to use PNGs.
Hmm... that could fix another problem I was having where I would need the loaded pictures to be automatically sized down. Thanks for the suggestion.
