I've found 2 bugs with BMP support.
Firstly, for 32bpp images the alpha channel can be replaced with uninitialised memory.
Secondly, for 24bpp images are incorrectly padded.
The fix for this is appended. I don't know how I go about getting write access to the source - so perhaps someone would apply this on my behalf.

Thanks for the patch. Sorry that it took awhile for it to be applied.
