Hi Adelaide,
Thanks for the feedback.
1. A new search engine with advanced features to search within catagories and by photographer will be updated within the next week, lightbox and hover view updates are also coming.

2. Yes, we do except some smaller photos, seeing that a large part of the stock photo market is web designers, and most webdesigners don't need 2400x2400 photos, and it's a shame to waste a perfectly wonderful shot if some one can use it! We do want to focus mostly on high res photos though (obviously), annd already have quite a few talented photographers contributing. 

3. As far as poor quality shots and keywords.... there were quite a few photos bulk uploaded (1000-3000) within the last 48 hours, and some photos were accepted that should not have been, we are going through as I type, those bad shots should be out of there within 24 hours....

Thanks alot for taking the time to give feedback.
