Okay, the Media Translation section is now visible in WPML settings. A few more questions:
1. Could you tell me exactly what settings to use if I don't want to use separate images for translations. I want to duplicate them across languages. I only want to translate the title, alt text and caption. The documentation explains this is possible but doesn't tell you what settings to use to achieve this. I'm finding the setting descriptions are not so clear, and I want to set everything up correctly this time.
In order to duplicate the exciting images to all languages, please go to WPML-> Settings-> Media Translation section, select all options, and click on the "Start" button.
Please check the second part of the Media Translation section for the new image's configuration. (Kindly check this hidden link)
Also, please don't forget to select the media translation options in the language side panel on the pages/posts editing screen. (Kindly check this hidden link)
I hope this helps you. If you need further info, please let me know.
