Image formats

Just an FYI post for those out there that don’t know.
 
BMP – raw image data, similar to WAV for audio, stands for Bitmap.
PNG – "lossless" compression for image data, similar to Apple Lossless, FLAC, etc. for audio, stands for Portable Network Graphics.
JPG/JPEG – "lossy" compression for image data, similar to MP3, AAC, WMA, etc. for audio, stands for Joint Photographic Experts Group.
GIF – "lossless" compression for image data, but limited to 256 colors. Great for little web icons and such, but horrible for anything with more than 256 colors. Stands for Graphic Interchange Format.
 
Moral of the story: use PNG unless you really care about space.
