Hi, I am currently in the process of setting up a shop for dog leads. I have spent ages taking photos of all the leads as they come in different colours. The colour is one of the variants for each lead and when I set up the products I have uploaded a photo for each different colour. What I want to happen is when someone clicks the color dropdown menu and selects blue, a photo of the blue lead shows. If they select red then a red lead shows etc. At the moment its just whatever colour is at the top of the list that shows regardless of what is selected on the dropdown menu. Does anyone know what I've done wrong here? Thanks
