I just uploaded version 0.5.5 of the Flickr Slideshow plugin. This version has a fix for the "This photo is currently unavailable"-bug. (Please contact me if it still occurs with this version so we can digg futher into it.) I deliberately write we, as I'm pleased to anounce that Marcel Peek and Koen De Voegt have teamed up with me in effort to bring you even better Flickr extensions. We also added a forum on http://joomla.universalplayground.eu/phpBB3
