Embed image signature line in Pocket Outlook?

[veedubguru]

Okay, I'm hopefully going to get an answer from someone who has successfully done this before.

I'm trying to put a web-hosted image as my signature in Outlook. I have an email account (pop) setup on the device, and have tried several ways and nothing works.

Here's what I've tried so far, and it never displays as anything but a link to the recipient.

http://www.mydomain.com/myimage

and

<img>http://www.mydomain.com/myimage</img>

Either way I go, it still doesn't display the image to the other person, only the link, and in the second format I tried it shows the HTML tags with the link between them. What am I doing wrong? Or can this even be done with Pocket Outlook?
