Re: "Can anyone confirm that images can be inserted in-line in an email on a
Mac running macOS Sonoma Version 14.6.1 using Intel silicon?"
Sorry I can not. Am restricted to using MacOS Ventura on my 2017 Mac. Seems, with photos, I can drag photos into an email I'm composing and they will display in amongst the text ok while I'm composing the email. However other types of file-attachments (.pdf etc.) display at the end of the message, in accordance with the settings I have in place.
Also: I have no control over how the recipient's eMail app will handle the display of attachments.
Their particular app settings may also influence what the viewer sees.

Re: "how do I send an email with a email image in the body of the email and NOT a icon"
Looking at a couple of Apple Support's online articles for MacOS Sonoma:
Add attachments to emails in Mail on Mac - Apple Support
Eg: says:
"Send photos in emails
- In the Mail app
on your Mac, open the message you’re writing. - Click the Photo Browser button
in the toolbar. - Drag a photo into your message.
"By default, Mail inserts images at their actual size. If different sizes are available, you can choose one from the pop-up menu located on the right side of the message header."
.... and then ...
"Put email attachments at the end of messages
In the Mail app
on your Mac, do one of the following:
- For the current message: Choose Edit > Attachments > Insert Attachments at End.
- For all messages: From the Message viewer, choose Edit > Attachments > Always Insert Attachments at End of Message (a tick shows it’s on)."
So you might want to check whether or not you have ticked "Always Insert Attachment at End of Message", and, if ticked, whether unticking that gives you more control.
Also:
Send large attachments in Mail on Mac - Apple Support
Eg: Says:
"You can change how attachments are displayed in the Compose window (this doesn’t determine how attachments are shown for your recipients).
✽. To display an attachment (such as a one-page PDF document or an image) as an icon, Control-click the attachment in your message, then choose View as Icon.
✽ To show the attachment again, Control-click it, then choose View in Place".
So we do have some control over whether an attachment shows as an icon, or in the place we put it.
All the best :-)
