You need to override the following file:
/includes/templates/template_default/common/tpl_header.php
Look for the following line in that file:
<div id="logo"><?php echo '<a href="' . HTTP_SERVER . DIR_WS_CATALOG . '">' . zen_image($template->get_template_dir(HEADER_LOGO_IMAGE, DIR_WS_TEMPLATE, $current_page_base,'images'). '/' . HEADER_LOGO_IMAGE, HEADER_ALT_TEXT) . '</a>'; ?></div>
```There are several ways to change the URL to point to the desired page you want.
For example, to point to the l*ogin page* instead of the *home page*, you can replace the above code with the following code instead.
```php
<div id="logo"><a href="<?php echo zen_href_link(FILENAME_LOGIN, '', 'SSL'); ?>"><?php echo zen_image($template->get_template_dir(HEADER_LOGO_IMAGE, DIR_WS_TEMPLATE, $current_page_base,'images'). '/' . HEADER_LOGO_IMAGE, HEADER_ALT_TEXT); ?></a></div>
```PS: It's not a good idea to change the logo image to point elsewhere other than the home page because most web users are already used to the default behavior, so use your own discretion.
