Any clues?


EDIT:

This is the part i think in images.php that may can rebuild the thumb:

Code: [Select]
      $type = ($thumb_tools == 1) ? "resize" : "create";
      if (($new_thumb_name === "" || $thumb_tools == 2) && file_exists(MEDIA_PATH."/".$cat_id."/".$new_name))
      {
        if (file_exists(THUMB_PATH."/".$cat_id."/".$new_name))
        {
          unlink(THUMB_PATH."/".$cat_id."/".$new_name);
        }

        if (copy(MEDIA_PATH."/".$cat_id."/".$new_name, THUMB_PATH."/".$cat_id."/".$new_name))
        {
          chmod(THUMB_PATH."/".$cat_id."/".$new_name, CHMOD_FILES);
          $new_thumb_name = $new_name;
          $type = "create";
        }

      }
      if ($new_thumb_name !== "")
      {
        @set_time_limit(90);
        $file = THUMB_PATH."/".$cat_id."/".$new_thumb_name;
        if (!$image_info = getimagesize($file))
        {
          $log[] = $lang['thumb_'.$type.'_error'];
        }
        else
        {
          if ($image_info[2] && $image_info[2] < 4)
          {
            if ($image_info[0] > $thumb_resize_dimension || $image_info[1] > $thumb_resize_dimension)
            {
              @unlink($file.".bak");
              if (resize_image($file, $thumb_resize_quality, $thumb_resize_dimension, $thumb_resize_type))
              {
                $image_info2 = getimagesize($file);
                $log[] = $lang['thumb_'.$type.'_success'];
              }
              else
              {
                $log[] = $lang['thumb_'.$type.'_error'];
              }
            }
            else
            {
              $log[] = $lang['thumb_'.$type.'_skipped'];
            }
          }
          else
          {
            $log[] = $lang['thumb_'.$type.'_skipped'];
          }
        }
      }
    }
    $image_resize = 0;
    $thumb_tools = 0;
  }

Don't trust in md5 it's unsafe change your 4i galerys password hash algorythm! second pw db field, create new hashes over some time, deny old hash. Help members that cry, send informationen mail to the rest. Camouflage new pw hash in cookie. Done!
