There are several ways you can set these as wallpapers on your computer. The easiest way is to right-click on the full-sized image (not the thumbnail) and select "Set as Wallpaper". If this will not work for you then you can save the image to your computer, open it in an image editor (like Paintbrush or PhotoShop), re-save the image as a BMP file, and set it manually. You should be able to do that by right clicking on your desktop, selecting "Properties" and under the "Background..." tab use the "Browse" button to select the image.
From this point forward, I request that all fan-wallpaper submissions be made in (at least) one of the standard wallpaper dimensions - such as 800x600, 1024x768, 1280x800, etc. All fan-wallpapers will be posted in the same size as they are received.
Please do not include other artists' fan-works in your wallpaper, unless you have permission from them to do so.
Until further notice, I will need to be more selective with the fan-wallpaper submissions that are added, due to the limited amount of time allotted to work on this website. I apologize for this, but it is the only way I can hope to work on other areas of the site.
