I've seen this done before in forums long past, and I thought it would be good to use here, since you have to host your images somewhere else and not directly on the site.
The rules are simple, count to 1000, but you have to use a photo. The number can't be a digital drawing, vector, or clip art.
It has to be a photo of the number existing somewhere in real life. It can be street signs, house numbers, statues, or anything else that is a photo. You can find the image through a google search, or take a photo of something yourself! Find something silly and you get extra credit!
