I'm using PNG files with SDL Image and no problem loading the alpha
channel from them. The greatest point on using PNG files is that they
are *MUCH* smaller than BMPs, and the image quality is way better than
with JPEG files.
Besides, does BMP files actually (or officially, for that matter)
support alpha channel?
