In the nifty SIGforum “Find => Advanced Search” utility there’s a “Post Types” region with these check boxes:
Polls
Photo Albums
Discussions

Hm…, I say to myself. So I tap the “New” folder icon and see the same three options (in different order):
Discussion
Poll
Photo Album

I’m familiar with Discussions and Polls of course, but how do Photo Albums work? I don’t recall seeing any threads so-labeled.

So back to the “Find => Advanced Search” utility, I un-clicked the Discussions and Polls check boxes, leaving only Photo Albums checked, then clicked “Search”, but nothing was found.

SIGforum does not host photo albums.

While it is a feature of the code for the Bulletin Board (forum), it is, and has not ever been implemented.

It's like a Jew's foreskin. It's implied, but is not a reality, in this universe...

Mazel Tov!

So, you're saying there used to be a photo album function but it got snipped?
