Problem: When I upload an image it duplicates it in my 3 different languages. As I use the same image for all languages, I would like to have only one image (without duplication) for all my languages.
Solution: Duplicated images will not make your system slower. the duplication has been implemented for easy management of media files (including Product images) in translated contents.
WPML Media is mandatory for WooCommerce Multilingual if you are also running it. Otherwise, it will not work smoothly.
Images are duplicated to avoid physical upload of images if you want to use the same image for translated/duplicate posts.
