    Watermarking was mentioned earlier and has been discussed before.
    There is a method of invisible watermarking that costs M-O-N-E-Y for a form of protection. I once subscribed to Digimarc for a basic watermark ID - I notice it now costs $50 per year and you can watermark 1000 images for that.
    Basically your ID number gets encoded into the image and programs can read it. Digimarc maintain your record and number and people can look up the owner of the watermark. I did it for a year or so and I'm attaching one of my watermarked images (NOT a map - sorry) so you can play with it. (My "Olly" sig has nothing to do with the Digimarc watermark btw)
    Basically something like Paintshop Pro has a View-Watermark pop down menu, if you use that on this image it should show my number (354519) and let you look up the Digimarc website registry of that number. Since I haven't maintained my payments for registry they seem to have lost me! No matter. The principle is demonstrable. PSP also puts a Copyright symbol on the PSP image window (that's nice!... erm)
    As an experiment you might like to try cropping and messing around with the image to see how much or little it takes to mess up the watermark? The theory being - I guess - that you have to do sufficient "damage" that makes your own original more provable as the original.

    Does that make sense????

    edit: this watermark was done back in 2003 so they may have improved the thing since then
