I found that 3dcafe has free photos that should work nicely with the backdrop tool, some requiring minimal cropping/sizing/etc. If you know of others, preferrably with little or no licensiing restrictions, post 'em here too! http://www.3dcafe.com/asp/photographs.asp Here's the applicable license restrictions: "All of the models/texture maps/software (referred herein as "datasets") available on 3DCAFE for download may be used royalty-free in your own work if you give proper credit to 3DCAFE.COM (i.e., Some models provided by 3DCAFE.com). If any of the datasets available on 3DCAFE are to be used commercially, you must contact us for licensing agreements. "
