[horde] Adding a banner graphic in horde webmail

[D G Teed]

Hi,

I'd like to add our logo to the top left corner screen of Horde webmail
1.0.1.  I see an FAQ item for this, but the answer was only
applicable to version 2.

I attempted to add an IMG tag to the common-header.inc
file but that didn't work.  It somehow caused the frame border
to appear and there was no logo.  It is probably touchy
with the style sheet.

Is there a new wisdom on the best way to add a logo to
the horde webmail screen.?
