Changing product's img when select characteristic

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.4

Hi,
I would like to know, is there any way to change product's image, when choose different characteristics. by "Edit variants" we are able to set different prices for different variants, but how can I change images?

Thanks so much

Hi,

When clicking on "Edit variants" you can see the listing of the variants, then when clicking on one of them you can see its details.
So here you can change the price as you already done, but you can too add images.

This way on frontend, when selecting the variant, it will display its images.

Thanks so much Xavier
