The wallpaper is available in various screen sizes:

• 1920 x 1200 pixels
• 1280 x 1024 pixels
• 1024 x 768 pixels

You find them anywhere and everywhere, but it’s not always worth the visit. To find a beautiful wallpaper for your computer (even more if it has seevral screens), you need to find reliable sources of nice wallpapers. I wrote down a few of the best ones here:

• The wallpaper section of National Geographic
• Digital Blasphemy (an age-old good source)
• Vlad Studio
• Adolescent Eyes whose work is shown below
• Mandolux, a photographer very attentive to the use of his pictures as dual screen wallpapers
• InterfaceLift has an excellent search engine
• dualscreenwallpaper.com and dualmonitorbackgrounds.com for dual screen personal computers
• MintyWhite
• Social Wallpapering

A simple reminder, if you have multiple screens, your PC will appreciate your using DisplayFusion, the perfect software to handle corectly those large picture files. Like I do it with this photo of a rbown snake eagle taken in Kenya (backlit by the setting sun).

Use Google.

Now, Google is able to search images by size. Just enter your screen size and you will be treated to a galore of images. If you also search for the word “wallpaper”, you are sure to find exactly what you need.

For my own 24″ screen, I could find brightly colored pictures or elegant designs. All designed to be wallpapers, even when no wide-audience web site had found it yet.

did I mention that it also works for dual-screen wallpapers? And did I mention that it’s free? (for a commercial use, this would not be an acceptable practice)

You can notice that these images being free of copyright will allow to produce impressive posters if you agree not to make it a commercial venture. Idea?

Look at the full set of the Windows 7 wallpapers. This is the upcoming version of Windows (after Windows Vista, it seems that Microsoft intends to switch back to a numbering scheme). Most of them may be colourful, but with very smooth surfaces where your icons will be appearing quite neatly and they offer a nice contrast.

So, I was quite interested when I stumbled upon the collection of pictures taken by the HiRise (High Resolution Imaging Science Experiment camera installed on board the Mars Reconnaissance Orbiter). Shooting photos of Mars surface, this photo camera brings extraordinary color images that provide nice patterns to be used as background for your Windows desktop (or even Linux or Mac desktop) and can be renewed quite regularly: Their catalog is available on the University of Arizona web site.

Furthermore, they provide an enormous resolution for their images which is a very good way to extract any size you may need for your extra-high-resolution background or to cover your 2- or 3-LCD display. Or even more. If you feel that there own selection of wallpapers is not enough:

• 800×600
• 1024×768
• 1152×864
• 1280×960
• 1440×1080
• 1600×1200
• 1920×1440
• 2048×1536
• 2560×1600

You can still stick to the original size (JPEG-2000 format images range between 0.5GB and 3GB).

And the good news is that there is no copyright restrictions, so you could do pretty much what you want with them: Really free desktop wallpapers.

Click on the thumbnails if you want to access the 1280*1024 versions

Those photos can be used freely for your own wallpaper (on your own computer).
