It was just the other day that a friend of mine noticed all of his Picasa albums were set to public. We went in to try and make them private, but it turns out that each album had to be done individually. And, when you have 87 albums it makes it nothing short of a long and annoying afternoon; after marking the first 10, we gave up with doing it manually. Now, we’re happy to share that Google recently updated Picasa to let you change the privacy of your albums all on one page.
To change your privacy settings for multiple albums at once, just visit All Albums page of your Picasa Web Albums account. Then Click the Edit visibility button.
An in-window pop-up will appear and it will list all of your albums along with their visibility. If you don’t want your albums showing up to anyone who might stumble across them, change the setting to either “Anyone with the link,” or “Private.”
