I would like to add our company's logo to the Zimbra OSS. I don't want to remove original Zimbra logo (I think when I do this change I have to use powered by Zimbra or Zimbra inside instead). Anyways, when I looked at base.html or html for the theme I would like to change, I see, that the part with logo is injected with some kind of magic. What I would like to do is to add my logo to the right of the Zimbra logo. Any idea on how to do this?
I understand basic HTML, but I feel I have to change some other part, not directly the theme itself.
