I used to do it when I was really big on roleplyaing, and I would download maps for a mapped roleplay. But now it seems just too much hassle, and I wont download a map unless I see a real need to, or I extremely like that map. And of coarse, to do that I need images. And if those images seem fantastic, I consider downloading.
meaning, if I download your map, it means you have got some sot of extraordinary talent.
