I downloaded a wallpaper from the wallpaper forum and want to use it as my boot logo. Here are the specifics .png, 320x480, RBG, and Alpha Channel: 0.

Pwnage says that's all I need, but isn't very specific on what they mean by alpha channel. When I select that image, the application crashes.

Am I doing something wrong, or are the picture settings not what it should be?
