Forum:Recent changes and recent images

Where is the extension for Recent changes and recent images which shows up on every page?

Wikia shows recent changes and the last three recent changes to the right of every page.

The coding shows the recent images as:
 * class = "WikiaActivityModule module" and

recent chgances as:
 * class = "tally counter" LatestActivityModule

Thank you. Errectstapler 17:29, March 18, 2011 (UTC)
 * update, I found this, for LatestActivityModule: : LatestActivityModule.class.php
 * and I found:
 * LatestPhotosModule.class.php on the same page. So this question can be closed. Errectstapler 17:31, March 18, 2011 (UTC)
