The structure of the content is connected to the content, not the languages itself. So by moving the content, it's moved for all languages. Can you explain a bit more about the issues you are seing with images? Are these images stored in the local folder? How are the links to the images stored (html content, content reference property, URL property, Link collection, custom property etc.).
I try to move content from thee media root to subfolder. I use master language when i get content, then I move content to subfolder. As a result, images are displayed only for one locale.
Could anybody help me? How to move content for all locales?
