BMP has no patents (unlike GIF & JPEG), so it's irrelevant that Microsoft
created it (originally for OS/2). BMP also supports compression, usually
with no loss of detail.
That said, GIF for line drawing, PNG for photos, and JPEG for photo where
fuzzy edges don't matter much.
I occasionally ask for BMP if I suspect I'm going to get a highly compressed
JPEG...
