Earnings for photos?

hello, i havent actually up loaded photo's to these sites yet but have looked into it what i found was you end up sending loads of pictures and don't get much back, there are loads of sites that have free pics for download eg photobucket etc so why pay when its free? some sites store your work and it can be sold to magazines or the highest bidder doesnt happen much though and the specifications for each pic can be confusing. just type in selling photos online lots come up. good luck hope you find a good paying one and remember to make sure your pics cant just be stolen and copied by others :)
