WPML allows you to translate images and other media. You will be able to provide replacement images for content in different languages and translate the meta texts of those images.
By default, WPML uses duplication to make media files available in all languages.
The options for translating media can be found at the bottom of the WPML -> Settings page.
Out-of-the-box translation of images and media
WPML core plugin allows you to manually translate the images and media in your content. In this case, you translate them just as any other part of your pages.
The Media Translation plugin allows you to upload “replacement” images for different translations. In this manner, you can translate the texts on the page using WPML’s Translation Management and provide replacement images for images that feature text which requires translation.
