DJ Image Slider Joomla Module Modification

Website relevant to project [login to view URL] We are looking to add a feature to the joomla module DJ Image Slider which we have installed on our website. Currently when you click on an image the image loads with the file name and standard layout. We want to add a facebook and twitter button on every image so it can be shared. The site is currently public however it will be password protected so the images must be able to be posted on the facebook page despite the security on the site.
