How can I embed an image from a remote server in my signature?

I want to have an image in my signature for certain emails, but not as an attachment. I want to edit the HTML of the signature so the img src is the remote server. How can I do this? eM Client only allows me to embed the image and includes it as an attachment to the email.

when creating a signature, right click and choose Insert - Image as link.

Not GOOD enough
