Okay, you want the subcategories' images to show in the listing, but not their names. Do you want the regular category images that can be uploaded in the category edit page? If so, all you need is to remove the text output. Copy /includes/modules/category_row.php to /includes/modules/your_template/category_row.php, find this```php
$list_box_contents[$row][$col] = array('params' => 'class="categoryListBoxContents"' . ' ' . 'style="width:' . $col_width . '%;"',
'text' => '<a href="' . zen_href_link(FILENAME_DEFAULT, $cPath_new) . '">' . zen_image(DIR_WS_IMAGES . $categories->fields['categories_image'], $categories->fields['categories_name'], SUBCATEGORY_IMAGE_WIDTH, SUBCATEGORY_IMAGE_HEIGHT) . '<br />' . $categories->fields['categories_name'] . '</a>');
. '<br />' . $categories->fields['categories_name']
to get this```php
$list_box_contents[$row][$col] = array('params' => 'class="categoryListBoxContents"' . ' ' . 'style="width:' . $col_width . '%;"',
'text' => '<a href="' . zen_href_link(FILENAME_DEFAULT, $cPath_new) . '">' . zen_image(DIR_WS_IMAGES . $categories->fields['categories_image'], $categories->fields['categories_name'], SUBCATEGORY_IMAGE_WIDTH, SUBCATEGORY_IMAGE_HEIGHT) . '</a>');
