A Mashable today says the Picasa-Blogger rebranding is part of the search company's new : Non-Google product names are being retired and replaced -- naturally -- with Google names.

Picasa, an image editor, and Blogger, a blogging platform, are two of Google's most popular free services. Within six weeks, Google will rename Picasa "Google Photos," and rebrand Blogger as "Google Blogs," Mashable says.

Google, when contacted by PCWorld, declined to comment on the report.

The rebranding makes sense, as users of these services -- Picasa in particular -- may be unaware that they're using a Google product. The expected integration of Picasa and Blogger with Google+ will likely coincide with the upcoming public launch of the social networking service, the report says.

Google has renamed its services in the past. For instance, VoIP service GrandCentral, purchased by Google in 2007, was in 2009.
