First up, thanks for the awesome plugin! I love the idea, and I'm sure I'll love the product.
The plugin seemed to install just fine. It asked for auth for my flickr account (which I of course granted). But every time I try to bring up my flickr through Canola, it gives me a message: "You are not logged in. Please switch to your browser and allow Canola-flickr access to your flickr account."
Now one thing I noticed was that in your comments, the plugin relies on python-flickrapi, which is not installed on my N800 (os2008 non-diablo). I enabled maemo-extras from gronmayer but i'm not seeing phython-flickrapi show up in my installable apps.
