Why wont this script upload all files?

[mybikeisace]

Using this code to upload files from a form. However it only uploads the last image, missing out any before hand.

            $uploadpath = get_img_path($username).$id."/";
            @mkdir($uploadpath);   

            foreach ($_FILES["pictures"]["error"] as $key => $error) {
               if ($error == UPLOAD_ERR_OK) {
                   $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
                    if( exif_imagetype($tmp_name) != IMAGETYPE_JPEG)
                             $errormsg=$errormsg."Unable to upload Picture ".($key+1)." at the moment. It is not a valid jpg image. Please edit the car to add the picture.<br>";
                    else
                    {
                   $name = $uploadpath.$key.".jpg";
                   //check file doesnt already exist
                   if (is_file($name))
                      @unlink($name);

                 $name = $uploadpath.($key+1).".jpg";       

                echo "tmp: $tmp_name name: $name <br>";
               if (!move_uploaded_file($tmp_name, $name))
                 $errormsg=$errormsg."unable to upload file";
                }
           }
        }

the echo line before move_uploaded_file is for debugin and reports the temp name, and upload name correctely so I cant figure out why it wont upload the first files.
