Need help

[ImportPassion]

Ok, I have photppost installed. What I want to do is check whether the post user has any pics in the photos table, if do, show an icon to those pics.

I have tried this in showthread.php right before
// display ratings if enabled

$myride2=$DB_site->query_first("select postuserid from thread WHERE threadid='$threadid'");
$postuserid2=$myride2[postuserid];
$myride=$DB_site->query_first("SELECT id FROM photos WHERE userid = '$postuserid2'");
$showmyride = $DB_site->num_rows($myride);


And I am using Logicians dynamic template hack to show the img, but I get an error that the num_rows is not a valid result resource.

Any ideas?

Thanks,
Derek
