I guess you were going to ask about FTP uploading. That's a little way off yet however, we will be getting a multi upload feature which will ease the burden of single uploads.
Err..., in my humble opinion, that's a priority. You got some real big shots hooked here, like Phildate, which is one of the big sellers at DT (and other RF's). People like them can't afford to upload 1 by 1 as it is now. As far as I can see, the snapshot spammers didn't discover this site yet. As for me, I will only upload images that have been approved at 2 sites (BS, DT, IS, SS, CS, 123RF) at least, that should ease the burden of inspecting. And no, I don't include Scandinavian and Stockphotomedia, they swallow *everything*.
If you want this site to reach the 50,000 landmark fast (which is a viable minimum), you should allow FTP. In return, you could ask photographers only to upload stuff that has been approved on other sites. In a later stage bulk HTTP upload by 10 or so is fine too, but *please* get rid of that 1 by 1 soon. I was considering the PhotoStore of ktools too, and as I remember, they have bulk upload or FTP.
