The FancyBoxThumbs extension displays thumbnailed images in a Mac-style "lightbox" that floats overtop of web page. This can create a more user friendly environment, where the user doesn't leave the page every time they click a thumbnail.


  • Download and place the file(s) in a directory called FancyBoxThumbs in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    require_once "$IP/extensions/FancyBoxThumbs/FancyBoxThumbs.php";
  • Configure as required.
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


You can set fancyBox options by setting a $fbtFancyBoxOptions variable in LocalSettings.php after setting the require_once above.

$fbtFancyBoxOptions = '{"openEffect":"elastic","closeEffect":"elastic","helpers":{"title":{"type":"inside"}}}';
