There was an older thread in the forums here about getting b2e to work with flickr. It took some fiddling with. That thread probably still applies to Phoenix. I'd look there first.

I've tried both the FAQ suggestions and the 3rd party suggestions (made by Tor, I think). The issue, I think, is that there is no longer a "default category" setting - only a default blog setting.

I had that problem.
I created a category under my default blog specifically for photos, and changed one of the files to name the default category to post under when emailing in the updates (the how to for that is in the original thread about it).

I couldnt post in the default at all, but this way seems to have worked.
