How to get Gallery 2.2.6 images into Random Image Display

Hi,

Could someone let me know how to get gallery2.2.6 images displayed into Random Images Block. Basically I am getting other images which are posted from other content click Classified Listings & Event Flyeys. So I would like to get the same type for Gallery 2.2.6 images if the images are allowed to be shown. For example, please look at this url. http://www.paradesi.org

Thanks
