I'm trying to create a wallpaper website. Now, I know there are lots and lots of wallpaper sites on the internet and each of these sites has various categories in them ranging from hd, 3d, cartoons, nature, celebrities, movies etc.
My question is: how do these websites get these wallpapers to post on their blogs?
Obviously they couldn't be creating them all themselves, so where do they get them?
I'm finding it hard to believe that one could just go to a wallpaper site, and download their 'free' wallpapers there and then put them up on his own site! Isn't that wrong? Or does 'free' mean you could do this?
I don't want to land into any copyright issues with anyone, and even if I may not be caught, I don't want to steal other people's work.
So please could anyone here help me clarify this issue?
Apart from designing them myself, how can I get these beautiful wallpapers to post on my own wallpaper website?
