Maybe this is somehow related to what you've found.
Yes that is what I found. When the image was garbled, I had no idea what it was. So I examine the data directly and cut/paste to a similar size .bmp template that has same header. Sure enough, it showed correctly. So it's not the data in the file that's bad, it's the extraction. Not a major issue but it's hard to know what you're replacing/modifying if the extraction is bad.
