Judging on the view of the pyramids, here's where it looks like the fountain *would* be in this photo...

EDIT: Jeff, I'm not accusing you of anything personally -- I just think wherever this originally came from may have fiddled with it.
SECOND EDIT: One very remote possibility would be one of those dual-prism type lenses that makes one item focus in much "nearer" than another (remember what they used in Darby o'Gill and the Little People?) That COULD make the fountain larger and and buidling smaller in *roughly* the same position... but that's a huuuuuuge longshot, and still doesn't explain the photoshopping.
