I've got images inserted into an email template - all good.
And I have an image with the following code

img src="/web/image?model=res.users&id=${user.id}&file-=image">.

When I send the email the image shows in the message trail for the Lead/opportunity within Odoo.However the email in the recipient's external email/inbox does not show the image.

Any feedback as to what's stripping the image?.

Thanks.
