Thread for the Picasa Gallery extension: http://extensions.pivotx.net/entry/66/picasagallery
Picasagallery is a frontend for your Picasa Web album. Together with your gmail-account you got one gigabyte of free webspace for your photos. With this extension you may integrate these photos directly into your PivotX website. In the control panel you choose the size of the thumbnails etc. and the extension has its own template system, which allows you to customize the look of the gallery.
