How to remove Poll Icon completely?

[kurti]

Hi,
(i have vB 3.7.4)
i'd like to remove the automatic appearing Poll Icon.
so that there can be a normal post icon instead.

i've tried removing this:

308 // show poll icon
309   if ($thread['pollid'] != 0)
310   {
311    $show['threadicon'] = true;
312    $thread['threadiconpath'] = "$stylevar[imgdir_misc]/poll_posticon.gif";
313    $thread['threadicontitle'] = $vbphrase['poll'];
314   }

from:
includes/functions_forumdisplay.php

but that made also all normal post icons disappear. (no idea why)


then i tried only removing line 312 and 313.
that worked fine in Firefox3...
but in Explorer7 the Poll icon is replaced with a little placeholder image (red x).


Can you please tell me what to change in this php file
to get rid of the Poll icon and the placeholder?
