i had seen this kind of module before in marketpalce of opencart but after i try to find again , i couldnt . maybe it has been deleted i dont know .
for example
on Category Page there is a big Image as Catalog page and there seems the products on it . when i click a product on it the page will go to the product page .
this module uses for car parts cataloges mostly . if anyone knows this module in marketpalce please tell me . thanks
