basicly its like this. there are a bunch of anime wallpaper sites out there... and most of them are orginal.... alot of them are.
www.animelayer.com is where most of them hang out...
www.abstractanime.com
www.bastardanime.com
www.desktopzero.com
www.everythinganime.com
they all have links for
www.animelayer.com . they have alot of helpful stuff to navigate PS and get a better understanding of it. these guys are good. they have sites out there were all they do is scan anime images, post them, and people take them and make wallpapers. there are rules to making them too. (sound lame but you will get flamed if you dont add shadows or your bg has too much or to little color) just post your wallpapers and see wut that have to say, just member they are not the nicest people. they can be harsh sometimes, but the will try to help you out.
now... i did some research for you (dont know why)
