My old script for pulling photos from your flickr account using the JavaScript badge code was outdated and excessively long - although it did the job it didn't do it very well.
My new version of the mini app designed for use with blog sidebars parses the javascript better, and allows for more customization of settings associated with the flickr badge itself.
Grab it here: flickrstream_v2.php
The new version includes comments on the important bits so you can see how it works.
