i know i have to set the max number, but i dont have to type each file in, that part doesn't matter, if you want to do it your way do this

PHP Code:

//Define Variables //
$qrback[1]="qrback1.jpg";
$qrback[2]="qrback2.jpg";
$qrback[3]="qrback3.jpg";
$qrback[4]="qrback4.jpg";
$numbgs = count($qrback);

// Generate randomness
$num = rand(1,$numbgs);

//output background
$qrback = "{imagesfolders}/$qrback[$num]"; 


most of this is just repetitive, you could just randomize the number, your way only REALLY matters if they were named for ex: boat.jpg, plane.gif, since then you'd have to define the names somehow, you have all the names "qrback#.jpg" so my way would be faster
