Another thing: featured blog post images aren't attached to the posts.
Check out: hidden link
Page "Post test". The image title and alt text are translated correcly, but the image isn't diplayed on the page. Is this maybe linked to wpml settings that do not copy the featured image or blog post design somehow?
I need your support to fix this, because there is no doc about this. AI doesn't understand too. And I don't want to use the "duplicate media" stuff that will multiply by x number the database size (for media library).
I have split this to a different ticket since it is not related to the original issue. You will need to duplicate the media to the secondary languages in order to use it for the translations. This does not copy an actual file to the other languages, just adds an entry in the database for the second languages. Please make sure when you edit the original post that the checkbox in the Languages box to "Duplicate Featured Image" is checked. If it is not, check the box and then save and it should copy to the translation.
This is how WPML is intended to work, but if you do not want to use the WPML duplicate functionality to copy the image, then you will need to find a custom solution.
WPML offers different media translation options to help manage images and media across multiple languages. Here’s what these options mean:
Translate existing media in all languages:
This allows you to provide different media (such as images, videos, or audio files) for each language. You can replace an image with a language-specific version (e.g., an English version of an infographic vs. a Spanish version).
This is useful when media content needs to be localized for different audiences.
Duplicate existing media for translated content:
This creates copies of the media files from the original language and assigns them to the translated posts/pages. It ensures that the same images/videos appear in all language versions without manually re-uploading them.
Duplicate the featured images for translated content:
This specifically duplicates the featured image of a post or page across all language versions. It keeps the same featured image for consistency, so if a blog post in English has a featured image, the translated versions (e.g., Spanish, French) will also have the same image. If you change the featured image in the original language, it updates automatically in all translations.
I hope this helps, please let me know if you have any further questions.
