Ask iBAM: Grouping Photos in iPhoto

I got an email a few days ago for the “Ask iBAM” crew from Bob. Not being a big iPhoto user, I thought I’d share to see what “the crew” knew. Here’s his question:

So I have a little question and was wondering if you could help.

I keep all of my photos nicely organized in iphoto with albums for everything. The problem is that I just can’t find a simple way to make sub-albums or sub-categories so I can clump certain albums together. It would be nice if I could have a “Family” album and then under that sub-album of “Holidays with the cousins” or “summer at home” or something like that.

Any suggestions would be great and thanks in advance.

As always, you guys rock and I appreciate you jumping in to help a fellow Mac user out.
