It's interesting that you got it to work with Paint Shop Pro. I tried it again with Photoshop Elements 2.0, and it still had a problem. But if I opened a waypoint BMP file that had been uploaded successfully before, then saved it in PSE, it did upload successfully to my Garmin, even though the DPI had changed. RLE wasn't enabled in either case. So you're right, the DPI isn't critical, but some other unknown parameter does make a difference. What that is, I have no idea. 16 x 16 is the only size that works for waypoints uploaded to the GPS; 24 x 24 is only acceptable for icons used by Mapsource.

I have found that it doesn't matter what the dpi is set to. I've even set it to zero and xImage accepts it as long as everything else is OK. The critical thing I found was that the file must not be compressed. If it is set to RLE in PSP X, xImage won't accept it. So, the icon must be a 16x16 (or 24x24?), 256 colour, uncompressed Windows bitmap. I’ve recently been trying to create a custom icon with Paint Shop Pro X.
