Затем /administrator/components/com_virtuemart/classes/ps_product_category.php
Примерно строка 920, функция function get_child_list($category_id) {, добавляем запросы на полную имагу категории. Вся функция

Далее заменяем вывод картинок:

для категории

<?php echo ps_product::image_tag(basename($product_full_image), 'class="browseProductImage" border="0" title="'.$product_name.'" alt="'.$product_name .'"',1,'product',210,210 ); ?>

 

 

для подкатегорий

				echo "\n";
			}
			echo '<div class="catlink">'.$category["category_name"].'</div><!-- end catlink -->';
			echo $category['number_of_products'];
			?>

 

для карточки товара не создавать

Основа http://forum.virtuemart.net/index.php?topic=84423.msg297547

Для карточки товара можно сделать следующее:
administrator/components/com_virtuemart/classes/ps_product.php, строка 1413

if(PSHOP_IMG_RESIZE_ENABLE == '1' && $resize==1) {

В карточке товара пишем

<a class="prodmainimage" href="/<?php echo 'components/com_virtuemart/shop_image/product/'.basename($product_full_image) ?>" rel="lightbox[<?php echo 'product'.$product_id ?>]"><?php echo ps_product::image_tag(basename($product_full_image), 'title="'.$product_name.'" alt="'.$product_name .'"',1,'product',500,500 );
 ?></a>

где 500 и 500 - размеры. Все.
