I have a product that can be customized. Let's say Im going to have a glass that can have the letters A-Z on it. Is there anyway when someone selects one of the letters, that the main image will change to a preset jpg. Basically I just want the image to change to show them what it will look like. I would have all the pictures already made up, i would just need it to switch jpg's. Please let me know if there is anyway to do this.
