I have searched the forums here and now I have to post my question because I cant find anything that will help me.

I have an image I would like to place on my background. I want it to fit the screen, not run off the screen and not be tiled. Everytime I try to make the image a single image(not tiled), it centers itself right behind my banner, at the top of the screen, and is just barely larger than the banner itself. I have a small version of the image as well as a very large version of the image. Is there anyway to auto-size the image so it fits the screen regardless of size of monitor you have? Cause at the moment I am using the tiled version and on my monitor the tiles run off the screen and cuts the last row of pictures.. where as on my wife's monitor they fit perfectly across.. mine is widescreen where hers is the square variety. Too much information for the question I asked but I felt like yakking. Could someone help please?
