There are many sites of wallpapers and screensavers but I never visited because I don't like what they choose and I don't use it either. But the main reason is that they have lots of advertisements. I came across with a result from the site Desktop Wallpapers and this is what they have written at the bottom of their screen:

This is another website:
Can someone explain to me how they claim that they do not intent to display any copyright protected images and at the same time they say that they don't own the copyrights for them and.... I'm exhausted!
All I know is that they give other people's work for free to catch attention for their site and make money from
the numerous advertisements they have at their sites.
I am rethinking about having ads at blogs. These sites create blogs and copy images from all over the web as a way to "laundry" the images and make it more difficult to find the author. This is not only unethical. I call it crime.
