The "User/Photo" feed you are expecting has it's own "<link>" elements. Further down, the section with all the (photo) entries starts, each of them with their own section of <link>s. Those are the ones you should inspect.

You also have to insert the ".../photoid/..." keyword into the URL, followed by the actual photo id. You can also find the photo id in the URL of the one-up photo view: http://picasaweb.google.com/115590752798736746987/RanoBe#* 5524709173728479538* To grab the entry for this photo: http://picasaweb.google.com/data/entry/api/user/115590752798736746987/photoid/5524709173728479538 Each photo itself, can also be a feed (or collection) of other things. By default, the feed for a photo: http://picasaweb.google.com/data/feed/api/user/115590752798736746987/photoid/5524709173728479538 would return itself and a collection of comment entries (if your photo had some). We also differentiate between the meta data of a photo (that comes back in the feeds and entries) and the actual media content (the image urls you have found).
