lave thumbnails med gdlib i Loop fra MySql array

Hej. Nu er jeg nået frem til at kunne lave en thumnail vha.

$image_path = "../upload/upload";
$image_name = $name;

function thumbnail($image_path, $thumb_path, $image_name, $thumb_width)
{
    $src_img = imagecreatefromjpeg("$image_path/$image_name");
    $origw = imagesx($src_img);
    $origh = imagesy($src_img);
    $new_w = $thumb_width;
    $diff = $origw/$new_w;
    $new_h = $new_w;
    $dst_img = imagecreate($new_w,$new_h);
    imagecopyresized($dst_img, $src_img, 0, 0, 0, 0, $new_w, $new_h, imagesx($src_img), imagesy($src_img));

    imagejpeg($dst_img, "$thumb_path/thm_$image_name");
    return true;
}
$img = thumbnail("$image_path","$image_path","$image_name","80");

Dog vil jeg gerne have den til at vise thumbnails af alle billeder i min database.
Her er min kode for at "printe" billederne på skærmen i fuld størrelse:

aabn_forbindelse_og_vaelgdb();
$sql = "SELECT * FROM filer order by userid";
$resultat = mysql_query($sql) or die(mysql_error());
//$optaelling = sql_spoerg_og_faa_svar($taeller_sql);
luk_forbindelse();
while($row = mysql_fetch_array($resultat)){

// do some thing here

$id = $row["userid"];
$name = $row["name"];
$descr = $row["descr"];
$type = $row["type"];
$dimension = $row["dimension"];
$image_dir = $row["bill_sti"];



//part 2

print "User Id : $id <br />";
print "Name : $name <br />";
print "Description : $descr <br />";
print "Type : $type<br />";
print "Billedets mål : $dimension <br />";
print "image is <img src='../upload".$image_dir."/".$name."'> <br /><br />";

Men i stedet for print "image is.... vil jeg gerne have den til at vise alle billeder i databasen som thumbnails - er dette muligt?
