I often see Picasa images embedded in forum messages, but I sometimes would like to access to the albums they come from.
Flicker allows this kind of request using their API,
flickr.photos.getInfo. You enter the CDN filename from the image link (
http://farmnumber.staticflickr.com/server/photo_id.jpg) as the
photo_id, and browse the information related.
Do you people know a way to achieve the same thing with Picasa?
