Show First image in userbrowselistings

[bowers01 +]

Hi,
Can someone please point me in the right direction for showing the first image in userbrowselistings, i assume i have to add something in here

$sSQL = "SELECT id,title,section,price,display,hitcount,dateadded,expiration,orderID,oType,oStatus,oProductID FROM ".PREFIX."listings LEFT JOIN ".PREFIX."orders ON orderID=oID WHERE owner = ".$userid." ". $where ." ORDER BY dateadded DESC";

But i am not sure on what to add?
Thanks for the help,
Nick
