I spent some time the other day putting together a plugin for Mephisto that would let me display a small selection of photos from my Flickr feed - you’ll see the results on the right side if you’re looking at this through my site.
Well, the first cut is done and seems to be working fine with a good response inside the Mephisto Google Group.
To install, you’ll need to change to your mephisto install’s directory and run
$ script/install plugin http://www.engross.org/svn/mephisto_plugins/mephisto_flickr_photo_stream/trunk/
then inside your template you’ll be able to use the following:
{% flickrphotostream feed: http://api.flickr.com/services/feeds/photos_public.gne?id=57966634@N00&format=rss_200 count: 6 %} 
{% endflickrphotostream %}I’m working on writing up some of the things I came across whilst I was working on it. I wasn’t happy with a few things (most importantly, the tests), and I’ve already started tinkering with the code again to improve it a little.
But, if you’re running Mephisto and want some Flickr goodness feel free to give it a try!
