Ok, I shall repeat.... why restrict yourself to photo specific cloud storage when there are much better, unlikely to disappear or change drastically options from major players like Microsoft, Google, Amazon.....?? As mentioned most of these come with more free storage than the photo cloud rip off artists and you have the option to store & back up many other file types other than photos. They also allow you to access files pretty much anywhere you have an internet or smart phone connection.
Here's a link to a review of the major 'players'. A good chart showing options for free storage & what it will cost if you need more.

As mentioned in my previous post, I have Google Drive & Windows One Drive. More storage then I'll ever use for free. And again, I've found the Microsoft One Drive <embed> feature the most flexible & best method to link photos on forums etc., once you figure it out....
