The RandomImagewithinCommons extension allows to display a randomized image per view including images that are stored at Creative Commons.


Set tag <riwc />


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


Use $wgriwc['size'] = '400px'; to set the default size to 400 pixel. If it not set, it will be displayed in 200 pixel width.

To ignore any picture, you can add in to the Category [[Category:riwc blacklist]] to put in on blacklist.
