• 4 bytes: some kind of application specific image type nr (?)
• 4 bytes: file size (same as after the 0x42 0x4D)
• Actual bitmap file

You might want to check if skipping the first 8 bytes is enough to get it to work, then I'd check if this is generic across all files (maybe there is more than one file type!)
