OK Zukerberg, I give up. Facebook App without authentication?

So, here's where I am at the moment: I've got a website which the client would like to reflect their Facebook galleries. No problem, I'm using FQL to pull all of the data on the albums and then display them all, click through to individual albums, lightbox for the pics, it's all good.

The problem is I'd rather the user didn't have to login to Facebook to view it. The App is owned by the FB account I'm pulling data from, all of the data is public as far as I can tell, but if the end user isn't logged into Facebook or hasn't authorised the app then they have to login (meaning if they don't have a FB account they can't view the gallery).

Any ideas? I'm not asking for ANY extended permissions, but I essentially need the offline_access permission (due to be deprecated, hence I'm not going down that route).
