There are a handful of plugins for Picasa Web Albums and self-hosted wordpress blogs, but none that I can see are what I'm looking for, which is very simple.

All I want is in the sidebar, a widget that shows the most recent albums. I should be able select how many albums are displayed. And the cover photo should display as the link (otherwise I could just grab the rss feed).

I'm not looking to embed in pages, or posts, just a sidebar widget.

Any ideas?
