Adding an image signature to an Email generated from VBA

Hi,

I have a project I'm working on which sends emails automatically from excel
using VBA.
The problem is that the mails generated doesn't include my signature.

Until today I was doing that using a pattern in html with a TEXT signature
I included.

Now I want to change that to include the default signature I have in outlook.
the problem is that signature is a picture so it can't be converted to html.

I want to try and solve the problem without any security warnings poping
out and stuff.
I want to keep using patterns of mails and if possible, to include my picture-signature
in those mails.

Is something like this possible?

thanks.
