Automatically share photos
Well, as you mentioned, there is no official or easy way to do this.
The only thing I can think of is to create a &quot;Shared Album&quot; (Go to the album tab in the photos app and click the &quot;+&quot; icon, then tap the three dots in the upper left and click &quot;Share Album&quot;). The only thing is you will manually have to add photos to that album (Which is easy to do, just go to the &quot;Library&quot; view and tap &quot;Select&quot;, select the photos, and then tap the share icon and &quot;Add to Album&quot;).
Hope this is helpful!
