Is it possible to display a different product image when a customer clicks on the "One-Time Purchase" option compared to when they click on the "Subscribe and Save" option?
There isn't a built-in feature that allows you to change the product image based on the purchase option selected in the subscription widget. However, it may be technically possible to implement this feature through customization.
