At least one of your problems here is:
$imagenum = $imagenum++;
This should simply be:
$imagenum++;
Or
$imagenum += 1;
In your $imagenum=$imagenum++ $imagenum will always end up as '1' due to
operator precedence.
You could also replace the while with a for loop:
for ( $imagenum=0; $imagenum<4; $imagenum++ {
//code here
}
