Maps

Hmm, dunno where to put this exactly but…

I’ve finally started work on my web-based RPG, (as in runs through the bowser, currently only using PHP/HTML, though when I get round to it, will be made spiffy with Flash).
Trouble is, I need some terrain for the game. Anyone know of a good place to grab maps from?

You can see the demo so far at:
http://redeck.sourceforge.net/finalrealms/
(It can be slow for 56k’ers, so is really intended for broadband/cable users)

I’m currently trying to get my head round the party battle system. X_x;
