Hi,

I would like to share this information to the community.
I have found a workaround to solve how add an image as an embebed image in Roundcube signature.

The trick is save the image like it were an emoticon, in the directory path_to_roundcube/program/js/tiny_mce/plugins/emotions/img/image_name.gif

The image must be a .gif file.

Next you can setup an HTML signature in Roundcube using something like this:
<a href="http://www.domain.com"><img src="https://your_server_URL/mail/program/js/tiny_mce/plugins/emotions/img/image_name.gif" alt="Image_Description" width="850" height="244" border="0" /></a>

I hope this helps somebody.

Many thanks Zhang for your great job and your support.

Regards
