resize of a random background
is there a way to display a random selected background with out having several different size backgrounds of the same background.... below is the code i have for displaying a random background....
<script language="JavaScript">document.open(); document.write("<body background = '" + bgimage + "' text = '" + text_color + "'>");</script>
there are 20 different backgrounds that are displayed at random each time the page is loaded or reloaded. is there a way to have the background resize to the users screensize without having 5 or 10 copies of the same background with different sizes....
