How to put categorie images in categories tab

Hi,
Does anyone knows how to put the caterorie images in the tpl_header.php?

I want to show in every page all the categories as images, i've tried to move the code from tpl_index_categories.php (that displays the images) to the tpl_header.php but I get the error divide by 0 that meens that he can't pass the value to calculate the numbers of categories to show and can't divide the available space.

thanks.

(I created a new thread because i couldn't correct the title of the other one...)

If it helps, the URL of the page is http://brunomachado.net/1301/, notice that I have a couple of categories (with no products or sub cat). what i want is to put the exact layout of the cats in the header, where the cat tags are

In /includes/modules/your_template/categories_tabs.php, this line

// create link to top level category
  $links_list[] = '<a class="' . $new_style . '" href="' . zen_href_link(FILENAME_DEFAULT, 'cPath=' . (int)$categories_tab->fields['categories_id']) . '">' . $categories_tab_current . '</a> ';

builds the link and its display. You will want to change the href to an img to display your image instead of text. Someone skilled in the intricacies of zc, php and html will have to describe exactly how to do that - choosing the correct image for the category and keeping the link intact.

Thanks a lot Glenn, couldn't find the correct module php file.
Zen Cart is new to me, but i'm a php, xhtml programmer, so I hope that it wont be a problem to change that.

For the record,
here is the solution,

first get the images from the db

$categories_tab_query = "select c.categories_id, cd.categories_name, c.categories_image from " .
TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd
                          where c.categories_id=cd.categories_id and c.parent_id= '0' and cd.language_id='" . (int)$_SESSION['languages_id'] . "' and c.categories_status='1'" .
$order_by;
$categories_tab = $db->Execute($categories_tab_query);

the in the list show them...

$links_list[] = '<a class="' . $new_style . '" href="' . zen_href_link(FILENAME_DEFAULT, 'cPath=' . (int)$categories_tab->fields['categories_id']) . '">' . $categories_tab_current . '</a> '. zen_image(DIR_WS_IMAGES . $categories_tab->fields['categories_image'], $categories_tab->fields['categories_name'], SUBCATEGORY_IMAGE_WIDTH, SUBCATEGORY_IMAGE_HEIGHT);

Once again, thanks Glenn

Where does this point to for the images? Is it /includes/template/mytemplate/images?
