Making thumbs same size

Hey hi!!. I have a few pages that uploads images to the apache server and makes a registry on a mysql database. Everything is going well just for a few details. When I make the upload for an image, it creates me a thumb image, but not as I want. For example, if I have an image that its of 2000 x 2000 px, the thumb created is 200 x 200, If I upload another with 300x300 px, my thumb will be 30x30 px, making look the gallery pretty bad. The only thing that I need is that all my thumbs were on the same size. I've tried to modify the thumb width and height size, but doesnt work.. Probably I am not undersatnding hoy to use the resampling() tool. here is my code. <?php include("connection.php"); //make variables avaliable $image_caption = $_POST['image_caption']; $image_username = $_POST['image_username']; $image_tempname = $_FILES['image_filename']['name']; $image_date = date($_POST['image_date']); $today= date("Y-m-d"); //upload image and check for image type $ImageDir="/var/www/apache2-default/images/"; $Imagethumb=$ImageDir."thumbs/"; $ImageName=$ImageDir . $image_tempname; if (move_uploaded_file($_FILES['image_filename']['tmp_name'],

                            $ImageName)) {

//get info about the image being uploaded list($width, $height, $type, $attr)= getimagesize($ImageName); //insert info into the table $insert= "insert into rsiis_images

           (image_caption,image_username,image_date,image_date_upload)
           values
           ('$image_caption','$image_username','$image_date','$today')";
           $insertresults=mysql_query($insert)
           or die(mysql_error());
           $lastpicid=mysql_insert_id();

           $newfilename=$ImageDir . $lastpicid .".jpg";
           if($type==2){
                       rename($ImageName, $newfilename);
           } else {
            if ($type==1){
               $image_old=imagecreatefromgif($ImageName);
           }elseif ($type==3){
               $image_old=imagecreatefrompng($ImageName);
           }

           //"convert the image to JPG

           $image_jpg=imagecreatetruecolor($width,$height);
           imagecopyresampled($image_jpg,$image_old, 0, 0, 0, 0, $width,

$height,$width,$height);

           imagejpeg($image_jpg,$newfilename);
           imagedestroy($image_old);
          imagedestroy($image_jpg);
           }

$newthumbname=$Imagethumb.$lastpicid.".jpg"; //get dimensions of the thumbnail $thumb_width=$width*0.10; $thumb_height=$height*.10; //Create thumbnail $largeimage=imagecreatefromjpeg($newfilename); $thumb=imagecreatetruecolor($thumb_width,$thumb_height); imagecopy($thumb, $largeimage, 0, 0, 0, 0,$width,$height);

           imagecopyresampled($thumb, $largeimage, 0, 0, 0, 0,

$thumb_width,$thumb_height,$width,$height);

                                    imagejpeg($thumb,$newthumbname);

imagedestroy($largeimage); imagedestroy($thumb); $url="location:showimage.php?id=".$lastpicid; header($url); } ?> thanks for your help
