For almost a year, I have been using a service called Zeemage (https://zeemage.com/). Zeemage is a web-based solution that enables live gallery-based access to all your cellular trail camera images by sending them to a Zeemage service via email.
You can generate one or more email addresses in Zeemage and send your trail camera images directly from cameras to these email addresses or forward them from your mailbox. When you have done it, the pictures and videos from different cameras will appear in the gallery. You no longer need to go through emails and open attachments separately. You can review tens or hundreds of images within minutes with no hassle.

Zeemage processes images, videos, text files, and just regular emails from trail cameras. You can map different cameras based on keywords in emails - for example, specific strings in the subject. I have set up 20 cameras to use a single Zeemage email address with different string identifiers.
Later, you can use filters to generate different views in the gallery or build unique views in the control room.

For login, Zeemage is using either Google or Apple logins. It is a subscription-based service with different volume and price point options.
Go to https://zeemage.com and sign up for a trial. I highly recommend you try it. With almost 20 cellular cameras, Zeemage made my life much easier.
Disclosure: I helped to test the solution, and for that, I received a complimentary subscription to the solution.
