Note: This version (for Joomla 1.5) does not have a few features, it's deprecated.
I recommend using a newer version, Gold Picasa Gallery for Joomla 2.5 or 3.0.
Missing features in version for J!1.5:
- Interation into article backend form, which allows you to add Picasa album after or before article.
- Picasa images browser for backend
- few small elements which do not even remember
- custom albums
