==SLURL Raster Image URL Generator==
I was rather interested in the raster images provided within SL and SLURL.com so I decided to figure out how to replicate it in such a way that it could be incorporated into tools and/or services outside the standard fair offered by Linden Labs.  At some point I may rewrite it to use PHP or offer tips to incorporate it into something like the WMS provider in MapGuide.
