Image from email signature is stripped

Image from email signature is stripped

Hello,

I have zoho corporate email account and have set a HTML signature for all my outgoing email. The signature contains inline image with <img src="data/png:......." />

When I compose the email, i get the signature by default. So it makes me believe that it works. When the email is received at the other side on google/zoho, I dont see the image. I inspected the html of the email and it shows
<img alt=""/> and no src attribute.

then i replaced the inline src with a url by hosting my image. The signature when designed on html,shows the image, i can see the image even when i compose the email. If the email is sent to gmail, the image is seen in the signature. But the image is not shown when the email is received on zoho inbox., instead the img tag on examining in the inbox shows that img tag receives and id out of the blue and there is no src.

Regards,
Naval.
