Tell us what you are trying to do?
I'm translating products to other languages, but product images aren't duplicated to the new products in second and third language.
Is there any documentation that you are following?
Thanks for contacting WPML forums support. I'll be glad to help you today.
1) I've checked this product (hidden link), and found the image is duplicated to all languages.
Would you please tell me how to check or reproduce the issue?
Also, please try the following steps on the products with the issue.
1- Edit the default language product
2- Select the Media Attachment options (Kindly check the attached screenshot)
3- Update the product
4- Update the translation
2) It's not related to the issue, but according to your Debug.info, the WP memory limit needs to be increased. PHP memory is fine, but WordPress uses 40Mb as default. Minimum requirements for WPML are 128Mb. (Kindly check this page https://wpml.org/home/minimum-requirements/)
Add this to the top of wp-config.php to increase WP memory:
