Problem:
The client is using a custom post type with Advanced Custom Fields Field Group that includes an Image Field but the images are not showing up on the translated custom posts.

Solution:
When translating ACF with WPML please use our ACF Multilingual Plugin.

The plugin will add a translation preference setting to each field.

Fields that do need to have the text translated will need to be set to "translate" while images for example can be set to "copy".

Then simply translate the fields with the WPML Translation Editor while translating a post or page.

Do avoid setting field groups to "translatable", as this would only be needed in order to translate the backend labels or in rare cases, like ACF Groups with select field options.
