I send e-mails with embedded images (via copy and paste into the emails) from my Windows7/Thunderbird to a colleague with Linux/Opera.
He says that he has the option to view mails that others send him with embedded images either as (a) embedded, or (b) attachments.
He says, however, this does not work on mails that I send him, that the images always are shown as embedded.
What setting to I have to switch on my Thunderbird Mail to allow his Opera Mail to view my embedded images as attachments?
