If your database table has a unique index then you can name the image using that index.... eg


again assuming there is an autoindexed field in your table

<?
$res=mysql_query("INSERT INTO $table ($fields)VALUES($values)");
$im_name=mysql_insert_id();
?>



now $im_name contains the 'id' of your insert and you can name the image with that.

else look at http://www.php.net/uniqid which will create a unique ID for you.
