I applied your patch for the preview pane according to:  http://lists.roundcube.net/mail-archive/roundcube.dev/2006/10/51/

When I view an email in the preview pane that has images. the images don't show and there is no options to view images as in the single email window.  Is that known issue or is it my configuration?  Also is there a way to resize the the pane so the pane is bigger than the email list even if its hard coded?  Thanks
