Radar Size?

Hi!
I used this script in my game
http://www.unifycommunity.com/wiki/index.php?title=Radar
and it works fine, except that the graphic i used in my game as the background appears as a thumbnail, too small for my game. Anyone know how to change this script?
Thanks!

The key line seems to be this:-

GUI.DrawTexture(Rect(mapCenter.x-32,mapCenter.y-32,64,64),radarBG);

If you replace the 64s with the size you want the graphic and the 32s with half of that size, you should be able to display any background you like (if I understand the script correctly).
