Hi, First, follow the screenshot given below. Now, paste the code given below in Custom CSS section (Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard. Code: .productlisting .pgallery .thumbnail li img, .thumbnail li img { width: 200px; height: 200px; } Note:- Use the same height and width in CSS code that you used for the thumbnails ( in screenshot).
