I am trying to embed a Flickr album but NationBuilder indicates that the album is "Not Embeddable."
In our tests we were able to embed a gallery on another nation successfully, but the same link in this nation results in "Not Embeddable" error.
Update - please see "Flickr Galleries Disappeared" for detailed information - Embedly has stopped supporting Flickr galleries so we are no longer able to embed them with just a link.
The way that Flickr embeds galleries has changed and we had a related issue recently crop up. We will consider this issue but in the meantime try the workaround suggested in the official response to the other public issue.
