Product add on with Image help

Anyone know a plugin that will work as intended , All I want is to add a product add-on to a product in the product window, I sell t shirt’s and at the product window I want to offer a left arm flag , Extendon’s product add on , I bought and is completely broken looks perfect click the add on with the image via a checkbox , it never totals up or adds the add on, doing it via radio totals it up but is unable to unselect . I bought the pro version from woo Commerce and zero image support ;(. I don’t wanna buy another plugin that’s not going to work, Any Suggestions ? thank You ,
