There are the IDs, but hidden from the user (not in the address bar). There is instead some other hash. Earlier I send photos by Google Photos and make "share" album by Picasa Web Albums. Each album had ID in Picasa Web Albums and all worked. This ID was not visible in the Google Photos. Previously, ID was created by album name. Some time ago, Google changed ID to fully digital (consisting of digits), but everything worked off until end of Picasa Web Albums (I can not preview the IDs now).Yes, by newly created albums there is no ID, so I will do more researches to see, if Google Photos can be implemented similar way like Picasa
Will be any update for Joomla! 2.5 version of Phoca Gallery (including Google Photos support)? I have a huge problem with updating one of my sites to Joomla! 3.x. Every time upgrade fails. For this reason, it is still Joomla! 2.5, and I try to secure this installation as much as can.
