Single image gallery for multilanguage page

Hi, do you recommend some approach for shared image gallery for multilanguage page? I do in a page blueprint:

header.photos:
  type: file
  label: Photos
  destination: '@self'
  multiple: true
  limit: 0
  accept:
    - image/*        

Which isnt shared across language versions. I might do page.media.images instead of my custom field page.header.photos but

1. I need to display only some specific images per gallery (ie.: photos and/or illustrations
2. it wouldn't be shared (visible) in admin anyway.

Thanks for any hint!
