With the Eden Eclipse wallpapers you can personalize your desktop.
Each wallpaper is available in different resoultions as platform
independent jpg format.
To install the wallpaper, click the link with your desktop resolution
and open the image within your browser, then right-click the image and
choose "set as desktop wallpaper" (this might vary depending on the
browser you use). Another possibility is to download the image and save
it to your harddrive, then open it in a picture-viewer (for example
irfanview) and use the tool's ability to set your desktop wallpaper.
