I installed the flickr gallery plug in today and have it running on my wp 1.5 install. It is exactly what I was looking for as far as flickr and wp image sharing.
The only thing that has me stumped is that there is a link to view an album as a slide show. This link does not go to the album slide show but to the most recent public uploads to flickr.
there is a album_id var that is not being passed for some reason.
