A few years ago I was messing around with some powerpoint files and I
found to my surprise that all the images it contained were in fact PNG.
I managed to search for the PNG header magic and extract all the images
from the presentation that way.  If they used JPEG the quality would
support, but the size would shrink.  BMP is just too bloated and doesn't
support transparency.
