My personal favorite for a backdrop is "Maps3.jpg". It has the most aspects of the room visible (console, platform, whirligig, etc.) and would make a great wrap-around. (Might have to crop off the direction arrows in the top left corner, the Google blurb in the bottom left corner, and that 'poke-you-in-the-eye' "Report a Problem" rectangle in the lower right corner.) But then with the wrap-around inside the TARDIS, that bit could end up - as they say - on the cutting room floor, to make it fit. (We should post that one in case the link ever goes dead, if that would be allowed.)
