Have you tried setting View>Display attachments inline?

If you really want attached images to appear in the body of the message they are attached to, go to View in the Menu bar (if you don't see the menu bar press ALT on your keyboard and it will pop up), and click Display attachments inline.

You should be aware, though, that setting attachments to open in messages automatically could give you some serious vulnerabilities.

Have you tried setting View>Display attachments inline?

Yes. However, it doesn't display in their original position but appended after the email. I would like it embedded as it intended as the orginal mail. Still, no remote content. Only those are attached, and images only.

My I know what kind of vulnerabilities/attack surface I opened to? All I know remote content might contains micro pixels that enable email tracking. I hope the vulnerabilities isn't theoretical but those happened in the past or very serious like RCE or zero click exploitation. Thank you.

Are these emails that you receive or emails that you have sent ?

If image is sent as an attachment then it can only display after the content if you have View>Display attachments inline enabled.

If image was inserted into the content of the email, it is not just an attachment. If receiving the email and images are shown as attachments and sender put them inline as part of content then maybe you are viewing using Plain text and not HTML. Check your view:

• 'View' > 'Message Body as' > Select 'Original HTML'

However, if you created an email using HTML but sent using plain text, then all images will appear as attachments because all html is stripped. Check your Send Options:

• Settings > Composition
• Under 'Sending format'
• Select : 'Both html and plain text'

Thank you for coming in to handle this, Toad-Hall.

Recieve

If image was inserted into the content of the email, it is not just an attachment. If receiving the email and images are shown as attachments and sender put them inline as part of content then maybe you are viewing using Plain text and not HTML. Check your view:

• 'View' > 'Message Body as' > Select 'Original HTML'

I'm viewing it with Original HTML.

Did sender send the email as html or plain text and did they send using a phone?

Select email so you can see it in Message Pane. Click on 'More' button and select 'View Source'. This will open in a new window.
