sounds like a great idea :) I think it depends on the author that uploads the image or someone willing to spend time to tag each of the +/- 600,000 photos !

It's up to the individual that uploads the photo to add tags and product information. Perhaps if everyone was made aware of this, and reminded often, it would eventually become a reality....but for now, there ain't no way anyone can ever possibly add all that info to the current photos, it is completely reliant on whomever posted the pic originally! I know for me, the more info I post, the fewer questions I get, and the easier my photos are to find in a search!
