[مغلق] Why does op tion 'Translate Media Library texts' exist?

Hi,

I’m a bit confused about the purpose of this setting toggle:
"Translate Media Library texts (alt, caption, title) when translating content."

In my case, even with this setting disabled, the Advanced Translation Editor already picks up and translates alt text of images included in posts just fine (see attached screenshot).

So I’m wondering — what’s the actual benefit of enabling this option?

Please give me a geek answer, I am very experienced with WordPress and WPML 🙂

Thanks,
Erik Molenaar
