Let’s say you have a girlfriend, and you went out on a special romantic camping trip with her. You also took plenty of pictures, some maybe candid, and uploaded them on Google’s Picasweb. Responsibly you selected the Unlisted album option while creating the album because you wanted to share it with only a few of your friends and nobody else.
However, you never realised that Unlisted for Picasa is not the same as Private. People can still view your Camping trip’s album if they have access to the hidden URL, which would be like:
Now Google claims that this is not an issue, because Unlisted doesn’t mean its Private. Unlisted means that anyone with an access to the authorized URL can view the album even without logging in. Unfortunately many of the users may not be able to read between the lines here. Moreover, this isn’t a new thing, it was raised perhaps back in 2006 as well.
The real risk is that anyone could visit your unlisted album by maybe accessing your browsing History (yeah, we all are supposed to clean history and not share computers, but does it happen always?). Another risk is that Google may list your unlisted link on Google search if its found on any public forum; case in point > Click the URL below:
The result gave me 9,780 hits of unlisted albums floating around accessible right through the web search! Now its upto you to decide whether Picasaweb serves your online photo gallery needs or not, because Google isn’t listening.
