Picasa is a photo organizer program produced by Google. It is available as a free download for Windows XP or 2000, and there is also a version available that runs on Linux. It's primary use is to catalog and browse collections of photos, but it also includes limited photo editing capabilites, and a whole slew of associated features such as producing CDs of images, uploading them, blogging about them, or printing them.

Picasa also works with other Google programs and services, such as Blogger (blogs!), PicasaWeb (online photo albums) and Google Earth (program for browsing aerial photos of the whole earth) to provide a very full photo management package.
