I'm trying to set a photo from my own pictures as my desktop background. In
Windows XP, when I have done this in the past, I tell it to center the
picture and the picture appears as my desktop background at its normal size.
When I set the same photo as my desktop background in Windows Vista, Vista
magnifies the photo so that it extends above the screen (thus you can only
see part of the picture) and looks very grainy. I've tried centering, fitting
to screen (it doesn't fit to the screen, either!) and tiling, and nothing
works. How can I get Vista to display the picture as the desktop background
in the correct size?
