I'm really surprised to hear that putting random white pixels into a map image doesn't work. What exactly is going haywire with that approach? Anybody care to give me an example?

I was surprised too. The server seems to include the province positions in the trn file, oddly. So all the provinces end up cluster together in one corner of the map once you look at the trn file at the client end.

Another possibility would be to do this on the client side when they want to upload the image.

Okay, web stuff is very far from being my forte. What's the idea here? The computer at the client end runs the program contained within the web page to alter the map image before it's uploaded, so that the actual data uploaded is already altered and hence small? Or something different?
