Signature Not Displaying

I have a form that requires a signature. When I send the signature in the email notifying the client, it displays:

Obviously, this is not going to display anything and I must cut and paste as follows to see the entered signature.

How can I fix this. I’d appreciate your help asap because I am on a deadline.
