equilibriumx Hi. Line 80 in this file is responsible for adding a logo:
<a href="./" id="gkLogo"> <img src="<?php echo $logo_image; ?>" alt="<?php echo $pageName; ?>" /> </a>
You can simply replace:
<?php echo $logo_image; ?>
with a path to a different logo image.
to add an image on error page add this code:
<img src="path_to_image" />
over or under the line:
<h2><?php echo $this->error->getCode(); ?></h2>
which will show error code.
