I have this part of code in my mail

<td style='background-color: #DEE6EC; background-image: url("{{ 'cid:cloud' }}"); background-repeat: no-repeat; background-position: right bottom;'>

The image is successfully loaded into the mail and I can see it but it is not uploaded to cid:cloud.

Also in mail a have

<img src="{{ 'cid:logo' }}" height="60px" border="0" alt="" style="display: block;">

And when i change cid:logo to cid:cloud my cloud image successfully loads in both places. How to fix that ?
