My suggestion is to stop using the Apple mail app. I switched to the gmail app and I have a choice. I can send my photos as attachments or embedded. Much better answer to this ridiculous dilemma
There simply is no such thing as «embedded» photos.
The closest thing are attached photos (everything, with the exception of the Subject line and some body text, are attachments, in emails) that are formatted inline with body text.
Unfortunately, there exists a very tiny subset of email clients (consisting [almost] exclusively of a single email client, and its derivatives, from a single [non-Apple] company)—which, incidentally, has seen no substantive upgrades in over a Decade—which prevents bulk attachment processing, under some standards compliant conditions, contrary to standards conformance expectations!
There can never be any fault associated with standards compliance!
However, old, non-up-to-date clients can, and often do, have issues with standards compliant emails due to the failings of such email clients! Such has been found to be the case with a very tiny subset of email clients (consisting [almost] exclusively of a single email client, and its derivatives, from a single [non-Apple] company)—which, incidentally, has seen no substantive upgrades in over a Decade!
