Product Add-Ons for WooCommerce

Hi, would be very useful when we set additional option and we make them to display as images and give an option that they can be multiselect example as checkboxes, at this moment when you set options and display them as image the user can select only 1 option if you have set 2 or more available options, or if is possible to make the checkboxes options to display also as images. thank you in advance
