     The most wallpapers on this site are 800 X 600
Here's the method to fit the wallpaper to your screen
[ 1024 X 768 or higher]:

START->SETTINGS->CONTROL PANEL->DISPLAY->BACKGROUND
in the "Display" drop-down menu choose "STRETCH".
That will make a smaller or bigger wallpaper automatically
adjust to fit your screen.
