Success
All you need to do is add an alpha channel to the 24 bpp bitmap image (*.bmp) you want to paste and replace the "compressed" image space of the 64-bit-OS saved gmp file. You need a photo editor that can add an alpha channel (GIMP, Photoshop, Paintshop?) and a hex editor to do the cutting/pasting. It's actually pretty straightforward.
If anyone is interested, I can make a tutorial. With more and more folks going to 64-bit OS (Vista/Win 7) this may become a problem for mapmakers with a 64-bit OS who want to overlay an image on to a map.
I think I can manage adding an alpha channel to the BMP's (I've done that before with creating custom company logo's). I have got GIMP.
But the HEX Editor stuff goes way beyond me. I would really like a tutorial on that part.
