Google gdata javascript API doesn’t support Picasa?

Oh, I just sadly find that Google gdata javascript API does not include support for Picasa = =.

There is a Picasa API which is in REST API style. However, it’s not easy to access it via javascript because of the following reasons:

  1. The browser’s same origin restriction and:
  2. Picasa API use only XML as submit and return data formats, no jsonp.

As some of Picasa GET APIs are atom feeds, you can use Google Ajax Feed API or Yahoo Query Language(YQL) to get and access them. However, it’s difficulty to do more things purely via javascript.
