Put images directly in notification e-mails

We’re sending out Notifications when a new post is put in a certain category.
In this post (which is template based), we have a few tiny images.

Now I’ve noticed that instead those small images are embedded in the e-mails, a link to them is in the mail.

I have found this post which unfornately doesn’t seem to have been answered.

Is there any setting I can take to have small images embedded to notification e-mails?

You mean to base64 encode those into data-uri in img tags ? That can be a lot of work for the server. I’d try this approach first in a plugin.


This seems quite risky based on the image size as well?

Agreed. If there was a possibility to send pictures inline this should only apply to small ones - ours are icon-like.
