My opinion is that, when we are talking about HD wallpapers, the best site where you can find plenty of them is HDwallpapers.net. You will find there only high-quality images, at the best resolution possible. Wallpapers on this website are organized on categories. Some of them are: Abstract, Computer, Movies, Nature and Landscapes, Travel and others.
I think that this is the best site of this type, because of the quality of the pictures. The organization on categories is a plus when you're trying to find something certain. The website is well designed, having a pleasant theme. What I also like is that the advertising is present only on the left part of the website while navigating through the wallpapers, under categories, so it is discomforting the user while navigating.
