There are many thing to like about GIO's photo tools, including the rotation tool.
Many images in the group I help manage arrive as mail attachments. Moving them to albums is convoluted; download, then upload again.
It's a waste of bandwidth & a PITA to have to go this route; after all, they are already stored in an album, albeit the "mail" one.
But there are real advantages to have imagery gathered together in a titled album re: a topic.
And if you strip the images from the mail to avoid duplicates consuming storage, important context is lost for the imagery.
So I propose/suggest:
The ideal outcome would be you could move mail imagery into regular albums. When you do so, in place of the imagery, the archived email would get a attached link to the new location. So you can look at the album, or the mail, and still get there.
You can build a regular album with either imagery in mail attachments or directly uploaded. Then, the "message" images have a link to the album location.
