I've tried adding my signature,jpg to the signature line option window under preferences. It shows that its been accepted in the picture box, I save it and it doesn't save. What's wrong?
The use of images in the signature block in the Comcast webmail has long been dysfunctional. I have never been able to get it to work. You might consider enabling the account in a desktop email client like Outlook or Thunderbird if the signature is important to you.
