          $size = getimagesize($source);
          $w = $size[0];
          $h = $size[1];
          switch($stype) {
              case 'gif':

              break;
          }
          $dimg = imagecreatetruecolor($nw, $nh);
          $wm = $w/$nw;
          $hm = $h/$nh;
          $h_height = $nh/2;
          $w_height = $nw/2;
          if($w> $h) {
              $adjusted_width = $w / $hm;
              $half_width = $adjusted_width / 2;
              $int_width = $half_width - $w_height;
              imagecopyresampled($dimg,$simg,-$int_width,0,0,0,$adjusted_width,$nh,$w,$h);
          } elseif(($w <$h) || ($w == $h)) {
              $adjusted_height = $h / $wm;
            $half_height = $adjusted_height / 2;
              $int_height = $half_height - $h_height;
         imagecopyresampled($dimg,$simg,0,-$int_height,0,0,$nw,$adjusted_height,$w,$h);
          } else {
              imagecopyresampled($dimg,$simg,0,0,0,0,$nw,$nh,$w,$h);
            }
          imagejpeg($dimg,$dest,100);
      }
?>
but i don't know where i can paste it to get all uploaded images to albums cropped by this script !
i suppose it may be somewhere in album.php or includes/class_upload.php file ....
please help

You shouldn't be modifying the .php files manually, because then upgrading vBulletin becomes a pain. You should look for hooks and use plugins instead.

Try investigating the /includes/functions_album.php file. There's a hook called "album_prepare_thumb" which would probably be a perfect place to use this code as a plugin.


How To Use Hooks

I would like to achieve the same, cropping thumbnails.

I have created a plugin, I have put the hook "album_prepare_thumb" in each template it needs to stay (or I guess it needs to stay.. ).

The PHP code I put in the plugin is the same as this post, just I do not manage to set the correct path for the archive to be cropped. Please, could someone help me, what should I put instead of "ORGINAL_IMAGE.jpg" ?

Thanks

PHP Code:
<? 
      cropImage(100, 100, 'ORGINAL_IMAGE.jpg', 'jpg', 'thums/CROPPED_IMAGE.jpg');
      function cropImage($nw, $nh, $source, $stype, $dest) { 
          $size = getimagesize($source); 
          $w = $size[0]; 
          $h = $size[1]; 
          switch($stype) { 
              case 'gif': 
              $simg = imagecreatefromgif($source); 
              break; 
              case 'jpg': 
              $simg = imagecreatefromjpeg($source); 
              break; 
              case 'png': 
              $simg = imagecreatefrompng($source); 
              break; 
          } 
          $dimg = imagecreatetruecolor($nw, $nh); 
          $wm = $w/$nw; 
          $hm = $h/$nh; 
          $h_height = $nh/2; 
          $w_height = $nw/2; 
          if($w> $h) { 
              $adjusted_width = $w / $hm; 
              $half_width = $adjusted_width / 2; 
              $int_width = $half_width - $w_height; 
              imagecopyresampled($dimg,$simg,-$int_width,0,0,0,$adjusted_width,$nh,$w,$h);
          } elseif(($w <$h) || ($w == $h)) { 
              $adjusted_height = $h / $wm; 
            $half_height = $adjusted_height / 2; 
              $int_height = $half_height - $h_height; 
         imagecopyresampled($dimg,$simg,0,-$int_height,0,0,$nw,$adjusted_height,$w,$h);
          } else { 
              imagecopyresampled($dimg,$simg,0,0,0,0,$nw,$nh,$w,$h); 
            } 
          imagejpeg($dimg,$dest,100); 
      } 
?>
