You need to move the <table> command out of the while loop (put it just before it), and then add <td></td> as the first part of the echo command after the line:
if($new == 'yes'){
and add <td></td> to the last part of the line:
echo "<td><img src=\"images/$list_pic\">__<a href=\"models_profile.php?id=$lady_id\">$first_name $last_name</a></td>";
This should force the results to display in the two columns.
I am assuming the if check is to decide which column the result should display in.
