Subscribe to Picasa Photo Feed in iPhoto '09 or '11?

A colleague uploaded 100+ photos to her Picasa account. I can view the photos and download them one ... at ... a ... time. I'd really like to download the entire Picasa album.

I found iPhoto '09's File > Subscribe to Photo Feed, but it's unhappy with Picasa's RSS URL:

A variety of Community posts and other forum notes from around the Web report this worked in iPhoto '08. But I've found no mention of using the Subscribe feature with iPhoto '09 or '11.

At this point, I'd welcome any way to do a bulk download from Picasa on Mac OS X 10.6.8.
