Browsing here and there and clicked onto photo of dancers ((think) in google - highlighted the picture and clicked on set as background. Now I dont want it as my background but cant get it off as there is no where to delete
In Windows XP, RIGHT-CLICK on the desktop, select PROPERTIES and then DESKTOP in the Display Properties. That is where you set what is displayed on the desktop.
With Vista or WIndows 7 it must be something similar but I don't have either of those to let you know exactly.
