Picasa Web Albums and the Google Talk gadget

The Picasa Web Albums What's New page has been updated with the information that:

Share photo albums in your instant messages
You can now share photo albums in your chats with the Google Talk Gadget. Paste a URL from Picasa Web Albums into your chat, and you can scroll through a slideshow of the album right in your conversation.

In addition to that, there's mention of the Picasa Web Albums data API on the same page - and indeed this is being pushed quite strongly since on every album page the footer has now been updated to have links to Terms of Use - Privacy Policy - Program Policies - Developer - Google Home.  So every user gets to see a link to developer information, even though to the vast majority of the users who are not computer developers, this will be of no use at all.
