Once again, TarHeelTech, there is no such actuality of photos/pictures being “embedded” within an email.
All there ever is are attachments.
These attachments can appear (a superficiality) in ways that look like some people’s concept of “attachments”, or they can appear (a superficiality) in ways that look like some people’s concept of “embedded”, or, more properly, inline with other components of an email message, such as formatted text.
This is part of what I meant when I wrote «I thought I could expect better of you.»
Formatting and rendering of email bodies and the attachments thereof, is but a superficiality.
There is no such thing as “embedded” content, in emails, unlike embedded content in webpages: having the HTML tags contain the coded form of an image, for instance, rather than referencing an image file.
That entire concept is non-existent, with regard to emails, at this time.
(There may be a time, in the future, when embedding [or whatever they may choose to call it] may become a part of the International Internet Standards that govern email creation and interchange. However, I have seen no evidence that any such is even being proposed, at this time.)
If, on the other hand, all you care about is the formatting (appearance) of an email, then use an email client that lets you format the appearance of your outgoing emails however you like.
You can even provide Feedback to Apple on what Formatting control you wish to have, when creating email within Apple Mail.
However, be aware that there is no International Internet Standard that forces the receiving email client to perform any specific formatting. Such may or may not have the affect you desired. Actually, if you want that much control, you should send a PDF of your email as a document. (I believe there was a proposal to use PDF as a type of rich-text email, but it doesn’t seem to have caught on, for one reason or another.)
Otherwise, you could actually try to invalidate my hypothesis, if you will:
- «Apple Mail is, and always has been, «send[ing] emails … where the photos are … attachments, like how it [has always] be[en] for years», even at those times, through the years, when this Outlook issue surfaced with previous iOS versions.»
(Hint: appearances, formatting, and other superficialities have absolutely no bearing upon this hypothesis.)
Now. Which shall it be.
