Doesn't work for me.
Here's my html
I use Yahoo Mail, can anyone tell me what I'm doing wrong, it just shows up as text at the moment and I did set the signature option to graphics.
I guess you have to enable html code and use this format for the image link.
it should work if you do that, but i have not tested it yet.
EDIT: ok mine works
you have to do it in your yahoo sig. just follow the link here : http://www.mailsigs.com/yahoo-email-signatures/signatures-in-yahoo.htm
