$images[1] = 'bkgrnd-default.gif';
$images[2] = 'bkgrnd-positive.gif';
$images[3] = 'bkgrnd-negative.gif';
do you query, get the result in a variable, I'll use $field
<img src="<?php echo $images[$field];?>" />
you could do some error checking to make sure the value in $field
exists in the $images array
