I've fixed this in CVS (it'll be in the beta and final release, as 
well as available now from HEAD) by simply using 
$registry->getParam('graphics') instead of introducing a new function.
Yes, well, if you'd like to contribute any patches that work well with 
Horde while making that easier, you'd be most welcome to.

Hiya,



IMP 4.0 ALPHA, running through a CMS system (and yes, it was hell to 
get it working through an existing CMS that wasn't Horde_Template 
based), whereby the "graphics" directory isn't a standard subdirectory 
of the IMP application root, which broke the MIME type icons.



This can easily be fixed by replacing the call to applicationWebPath 
in lib/Horde/MIME/Viewer.php, at about line 423 to a new function 
called applicationGraphicsPath, and making that new function access 
the graphics path instead of the webroot path, and appending 
'/graphics' onto it, ie:



     function applicationGraphicsPath($path, $app = null)

     {

         if (!isset($app)) {

             $app = $this->_currentApp;

         }



         if (!$this->applications[$app]['graphics']) {

             return str_replace('%application%', 
$this->applications[$app]['webroot'].'/graphics', $path);

         } else {

             return str_replace('%application%', 
$this->applications[$app]['graphics'], $path);

         }

     }



I've done this for $client running Horde stuff, and it works for me.



Yours,



Kev, oRe Net.
