The Flickr Slideshow plug-in for Joomla 1.5 is a free open source plug-in to display photo's from your Flickr account on your Joomla 1.5 website. It uses the phpFlickr library, Slimbox (a lightweight visual lightbox clone) and the TripTracker slideshow scripts to aquire and display the photo's. Single photo's and even complete sets can be displayed by use of a simple line of code (e.g. [flickr set=1234567890]). In contrast to other Joomla Flickr plugins, this plugin doesn't require editing the website template. Simply install the plugin, enter your Flickr API key (which you can get here) and username, enable the plug-in and go for your life!(see the demo for instructions)
