George isn't thrilled that Google+ is taking over Picasa and posting them online. Leo suspects that Google plans on phasing out PicasaWeb in favor of Google+ posting. Leo suggests going over to PicasaWeb and marking his pictures private. When he goes to PicasaWeb.com, he'll be sent to Google+ initially. However, there will be a link to go back to PicasaWeb and he can then set all of his images to private.
There's also Picasa the program, which will enable him to not only manage the privacy of his images, but also download them back en masse. For information on setting his security on Picasa/Google+, check out this Google Tech Note and this Tech note.
