So here is something I’ve come across and installed recently. Written by somebody called lumis (David Rencher), it can be found here. Respect to lumis.
lumis*Gallery is a PHP based script which allows flickr members to display the photos they have uploaded to flickr on there own “personal” website. lumis Gallery also allows Flickr members to use flickr as a Content Management System (CMS) for your personal Photo Blog. lumis Gallery uses the flickr API to pull in information from flickr without actually loading the photos to your web server. lumis*Gallery is customizable through the main template files and the CSS files so you can match lumis*Gallery to your sites look and layout.
