[Resolved] Black thumbnaisl

Problem:
The client is experiencing an issue with black thumbnails on their translated page. They attempted to duplicate featured pictures in WPML > Settings > Media translation, but it didn't resolve the issue. The thumbnails remain black on the translated page, and the client is looking for a way to fix this issue massively instead of one by one.
Solution:
First, ensure that the translation is marked as "Update needed" and then click on it to re-save the translation. If this does not resolve the issue, try the following steps:
1. Go to the product in the default language, click on "quick edit", and update.
2. If the above does not work, switch to the secondary language, go to products, click on "quick edit", and update there.
If either of the above solutions works, you can bulk select the products and then do a bulk "quick update".
Alternatively, you can go to WPML->Translation Management, filter by products, select the products in question, and send for automatic translation. If they are already translated 100%, no credits should be charged, though it's recommended to test this with a small batch first.

If these solutions do not apply to your case or seem outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket.
