Prouct page images different size to listing page?

Hi. I'd Like to make the image size for my product pages different to the image size on a listings page. At the moment i can't see a way to do this.

You'll notice on the first attached screenshot (eg1, which shows a listings page) that the image for Black Dress is the same size as the same image on the second screenshot (a product page). How do i set it so the listings page displays a different size image to the product page (but not the same size as the thumbnail image seen at the right of eg2)?

Thanks.

Help needed asap please.

If you go in the tab "Files" of the configuration of HikaShop, you can configure a different image size for listings (thumbnails size) and the product page (image on the product page). Make sure that you're using a recent version of HikaShop as previous versions didn't had that possibility.

I know this already. The problem I'm having is that the Image Size options sets the size for the image in listings pages and on product pages. I want the size to be different on these two page types. For example, on this website> www.asos.com/Women/Dresses/Cat/pgecategory.aspx?cid=8799 you can see that the images on this listing page are all a set size. If you click on one you'll be taken to it's product page where the image is bigger than it was on the listings page. This is what i want to achieve but, as far as i can tell, setting the image size on hikashop (under the "files" tab) sets one size for both the listings and product page. How can i set a different size for images when they are on a listings page to when they are on a product page?

By just setting a different size for the "product page image" and "thumbnails" settings on that "files" tab.
If you don't have the "product page image" settings, then you're probably using an old version of HikaShop and you should update.

Thanks very much. My confusion was with the term thumbnail. I thought that only referred to the size of the image when it showed up in the lightbox when clicked on the product page. Much appreciated
