After the preview looks rather interesting, I was not able to install the component. Through the backend, I have tried it via package installation and direct (installation from directory) - both failed. The package installation approach could not find any package installation file. So, the downloaded file must necesarily be easy installable or there must at least be an installation procedure manual.

This is a powerful extension!
It can show public OR hidden (didn't test private) Picasa galleries from the RSS URL provided by Picasa.

This is unusual in that most other tools won't show Picasa albums that are Hidden. A useful feature when you have many many albums but don't want to show them all when they view your public albums, and still show them in Joomla site.

PROBLEM
The only problem is that this is not very usable.
It requires a MENU LINK to each Picasa Album for it to work.

It would be much more useful is this were a plugin I could embed into any content item.
OR
A component that could let you build all these RSS links and then show them in the site as a group of albums to be clicked into.

Currently it requires pretty crazy building of menu items and then republishing these menus in a module, which is way too complex.

I work in a content-centric environment so adding albums directly to content via plugin {moocasa rss='http://picasaweb.google.com/data/feed/base/user/xxx/albumid/xxx?alt=rss&kind=photo&authkey=xxx=en_US'}
would be much more useful.
