Oh no - this one's a stinker! - not really. Do you need to know how to put this on your desktop? There are a number of ways to set the chosen wallpaper as your desktop wallpaper / background. One way is to right click the wallpaper below and then select 'save target as...' (IE & Opera) or 'save link as...' (Firefox). If you do this - don't forget where you saved it! Next goto your computers display control panel and set the background to the image you just saved.
A different way altogether is to right click the background below, from here choose 'save image as...' or 'set as Desktop Background' or 'Set as Background'. When you're ready - you'll know what to do. I'm routing for you.You know already I'm sure. I'll be quiet then.
