I have two random numbers that determine how many images are shown in two columns.
$set1 = mt_rand(1,$max);
$set2 = mt_rand(1,$max);
I forgot how to make a modded variable to change the loop length each time it's run:
 for ($z = 1; $z <= 2; $z++){ 
for ($pieces = 1; $set.$z; $pieces++){     
      $device .= "<img src= {$direct}{$dfiles[$pieces]} alt=''/>
      ";
    }
}
can somebody help?
