Thanks for including the link at the end.
I ran into this little surprise a few days ago, and after firing off a little hate mail to Google (both to show displeasure with the switch, as well as frustration at the lack of a “Use Old Version” option), I found the old version URL on another site.
I really hope that the old interface doesn’t get phased out completely, but looking at Google’s track record, that’s likely to happen as they try to force users of other services to G+, which it seems they’re trying to turn into a hub of sorts.
As a current subscriber for an extended storage plan, this switch has me in the early stages of planning a switch of my own: from a Picasa Web Albums storage plan to a Zenfolio account.
Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
