I don't need a quick-fix for my site but thought I should tell you about this... unless I've missed some kind of back-end setting which controls it.
If I'm not logged in at mysite.com/ guardians/albums then I can happily browse through the 'Other Albums'
..but if I click the Avatar / Cover / Story photos I get asked to login and then if I try instead to click one of the 'Other Albums' suddenly I can't view those either without logging in.
Can this behaviour be consistent? Either you do, or do not, need to login to see event albums. My preference would be no login required (although I suspect some others might prefer login required).... most important thing though is consistency which seems to be missing here....
