WPML Media Translation allows to choose images and other media for translated content. You will be able to provide replacement images for content in different languages and translate the meta texts of those images.
You would use the WordPress editor to edit translations. There, you can upload different images for different translations.
However, when you use WPML’s Translation Management, you don’t edit each translation in the WordPress editor. You edit translations in a dedicated editor for translation (inside WPML or by a translation service). In that case, you need a separate tool to provide translation for images. This is WPML Media Translation.
Some of your content may include images containing text (i.e., screenshots of user interface items) that must be presented in different languages.
