Help with the Product images

Hi, I read through some of the forum threads and can't seem to fix the issue I have with the images on the product page. My problem is that images under hikashop_small_image_div and hikashop_main_image_thumb_div are of the same size. I set the thumb size to 50 and product image size to 100x200 from config -> File. Please see the screenshot attached. I am using the Default Product layout. Really appreciate your help on this matter.

thanks

Nicols,

Thanks for the reply. Sorry, if I didn't make it clear my issue. The styling in the link you provided changes the size of the thumb images. I am fine with the 25px height of the thumb images. As you could see from my screenshot there are 8 thumbs which are displayed just fine. As you hover over any thumb image, the corresponding image is displayed in the img control centered above the thumbs. I would like to change the height and width of the image control centered above the thumb images. But I couldn't find a way to change the size. I hope I made it clear. Thanks for your help.

thanks
