Google is full of API's, allowing users to hook up pieces of information and build their own tools and applications that access Google's services.

Google has publicly opened access to Picasa Web Albums via the Picasa Web Albums data API. What does this mean to you? Well, if you've been thinking about a way to integrate photos and tags into some kind of network or application, show photos together with comments on a website, or generating automatic tags based on a photo description, you can now access your albums, photos, comments and tags through the GData API.

A great use of the Picasa Web integration can be found at Picnik, the online photo editing tool. The team there has integrated in the new Google API so that users can load and save photos to and from a Google Picasa Web albums account, in addition to Flickr.

If you come across any other online location that has integrated Picasa into their tool, or if you have, drop us a line and let us know about it.
