Image or attachment

When I paste a particular image into replies, sometimes it shows, sometimes it gets converted to an attachment. The setting of HTML has already been chosen in Menu;Message;Format. How (else) can I get control over whether an image shows or it’s changed to an attachment ?

If the setting for replies is plain text, the image will be added as an attachment.

If the setting for replies is HTML, the image will be added as an embedded image.

You can set this in Menu > Settings > Mail > Compose > Message Format. Just set both the HTML, and pasting an image will always be embedded in the message.

Thank you for the guide; however in my EmClient, the steps are slightly different : Menu (in the program, NOT in the email reply); Settings; Mail; Compose; Mail Format; Mail format for reply; HTML; Apply

Yes, Menu > Settings > Mail > Compose.
