You make 1000 a month from this site? I'm very impressed. I feel like I should be doing something with the gigs of photos I have sitting on my computer now...
I wouldn't try to sell them - there's a lot of supply in that market right now. But people will always visit free once they know about it - it's then your job to figure out how to monetize them while keeping the nuisance factor for the user to a minimum.
That said, my site seems to get picked up in an unhealthy number of "top free images for your website" type list articles - I'm not sure if other sites would get picked up at the same rate, but you could always try.
