What a peach of a wallpaper don't you think? I suppose you what to know how to get it on the desktop now. You can set the wallpaper as you desktop in a number of different ways. You can either right click background wallpaper below and then click 'save target as...' (IE & Opera) or 'save link as...' (Firefox). Please remember where you save it to!Then go to wherever you set the background for you particular computer / operating system and select the image.
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 the time comes - you'll know what to do. I trust you. You probably already know in fact. I'll shut it now then.
