Problem: The client initially developed a website in French and later added Dutch and English. They encountered issues translating the ALT tags of images using the WPML editor, despite enabling the option to 'Translate Media Library Texts with Posts'. The ALT tags were not appearing in the editor, and the client wanted to avoid translating each image individually. Solution: We advised the client to ensure that the option 'Translate Media Library Texts with Posts' is activated in WPML -> Settings -> Media Translation. This setting allows for the translation of media meta-information using the WPML editor. Additionally, meta-information for any media can be edited in the library by changing the language in the top administration bar or using the WPML Media Translation add-on. It was also noted that the Divi widget might remove the ALT metadata from images, making them unavailable in the WPML post translation. Therefore, the recommended approach is to use Media Translation for images that could not be translated with the 'Translate Media Library Texts with Posts' option.
