woocommerce page customization

I am experienced with Wordpress, PHP etc but just finding my way around WooCommerce and looking for advice.I have developed a system where a user can upload a photo, pan, zoom, add text and save it. I am completely stuck on how exactly to go about adding this system to a product in WooCommerce on a product page. It does not effect the price etc its just so the customer can customize an image then order it for print. Any advice or guidance of the best go about this to achieve this would be greatly appreciated.
