If you have been interested in stock photography but have not been able to get in, you should check out DepositPhotos. They are currently running a new photographer promotion that pays you to upload your stock photos. This is payment just to upload, so it does not affect your sales. You will also get their standard royalties offered when your photos sell.
So if you want to sell your photos online, this site is paying you to get started. Check it out.
Well, this is what many other agencies tried. And it sometimes works. Just pay attention to frauds that may happen.
This program seems to be doing well and the site is already seeing sales.
