An alternate way to do the same is:

$cats[1] = array('moonlight.jpg' .......);
$cats[2] = array('foobar' .......);
$cats[3] = array(...);

You're missing a "]" here, Rik!

foreach($cats[ $_GET['cat'] ] as $img) echo $img;

Oh no! Now all I say is suspect, and therefor should not be followed.
Forget what I said, having $cat_1 & $cat_2 like variable names must be a
great idea :).
