Assets: option to have assets "version-less"

Some assets don't feature any text so they shouldn't be associated with a specific version.

Checkbox only visible in form to edit for staff
Still store the image in Japanese image field
With javascript, when the checkbox is checked, all images fields get hidden except the Japanese one (label could be changed for visual)
Would show up when filtering by any language ("or" in queryset)
Under fields details in ItemView, make sure the verbose_name just says "Image" not "Japanese"
