First of all sorry if this was posted before, but I was unable to find this type of problem.

I am trying to add signature to e-mail accounts, and because the signature will be an image, in JPG format, I have uploaded all signatures to /opt/zimbra/jetty/webapps/zimbra/public. All of the files are accessible via http://host.domain.com/public/filename.jpg or https://host.domain.com/public/filename.jpg

Also there are no problems adding the signature, when I add the location the picture pop up. I set the signature on new message, and save the signature...

The problem start when I start writing new message....the signature is shown as -- and when I send the email the signature is also shown as --

Please help
