Heyah 
On veer.com when you are looking at the detail of a photo, there is a flash viewer, which allows you to pan through the image, and the better quality version downloads after you zoom in, or move the image around.
Its fairly simple to move the image around, and zoom in - but how do they do it to control the download of the image?
Heres a link but I dont know if you have to sign in to view this page, I dont think so: http://www.veer.com/products/detail.aspx?image=CBP1005627
