Numerous sites like http://www.bigstockphoto.com/ and http://dreamstime.com/ (possibly others) claim to pay you for photos that you submit.

How it works:
1. Submit any hi-res photo or vector image (like using Adobe Illustrator)
2. If your photos/images get downloaded, you can earn up to US$1 for each downloaded picture you've submitted. They transfer to your PayPal account.

There are some rules that you need to follow (like you cannot submit pics consisting of brand names etc.) but i'm not too sure about that.

Just want to know if anyone has been using this to any success or not.

maybe those in the photography forum might know best.

It looks ok to me. They are acting like middle man. Photograhers get paid a small sum of what they earned from your photo. They charge 1.40- 2.50 per pic whil giving photograher 50 cents per download. Why not. Its good business.

There's sxc.hu.
It gives images for free.

On the contrary, if you're reknown enough, Getty Images might have you on commission to make 20+ full multilayer images to sell at... like RM2400 a disc.
