I was able to get the image to show. The problem lied in the mail.css file in the skin folder. There was no css information regarding the quota display. It seems as if you had to put this in manually as when I downloaded the roundcube code. Additionally, when I added the code from the trac site (trac.roundecube.com) in the mail.css file, I did not put the url path to the disk quota image in quotation as in url("path/to/disk/storage/icon"); Now I have a new problem. It is saying that the disk usage is unlimited, but I have set the quota size for the mail box in postfixadmin. Any assistance in this regard would be greatly appreciated. I truly appreciate the assistance I have already received.
