Oh, heck, there are all sorts of places out there. Doombuggies.com is for more Haunted Mansion stuff one might ever need, for instance, though it's more Halloweenish.
One really good place people post pics, of Disney and all sorts of other things, is
http://www.webshots.com/homepage.html -- just do a search for Disney and you can get a host of not only pics of strangers standing in front of things, but really good amateur photos of Disney locations, large enough for wallpaper in many cases. (Hmmm. Wonder if Rowdy will say, "I remember that day when I was helping Goofy! I didn't know that pic would be online!" about some pic or other.)
It's been wonderful for things like pics of the Not So Scary Halloween Party.
