In our embed code it looks like this:
<a href="https://www.emailtimers.com"><img src="http://emtmr.co/88e8c47a7cd9304b" alt="emailtimers.com" /></a>
If you remove <a href="https://www.emailtimers.com"> and then the </a> at the end you can use the image without a link that comes back to our site.
Or you can simply change the <a href="http://www.OtherDomain.com"> if you want to point it to another site.
