Picasa Web Albums - Linked Galleries

Picasa Web Albums have added a new feature - that of linked galleries.  These show up as a list on the right hand side of your public gallery page, and are simply links to other peoples public galleries.  You can see an example of this at the Documenting Picasa albums.

When you add a new user to your favorites then you are offered the choice of also displaying this in your Linked Galleries list, though as the dialog notes, you can always add it later.  You do this by going to your favorites list, which has has a new column added offering "show link on my gallery" for each entry.
