Thank you for your answer but if I change in customizing product page Woocommerce Options > Single product > Right side, to no sidebar, picture of woocommerce product getting bigger, if I change back to Right sidebar, the picture is getting smaller. I really like option No Sidebar, how product description and options are looking, but I don’t like that woocommerce is making single product picture so huge when I choose that, so this code is not working.
.woocommerce div.product div.images img {
width: 343px;
height: 500px;
}
Please help with one more question, how can I make website full screen but not 1200 px x. I really want to make 1900px if possible? How can I do that?
