Restrict image field to images with tag

In the field settings additionally offer under Validations: “Require images with tag(s)”. Admin enters 1+ tags. Now:

  • When the editor opens the gallery selector, it forces those tags to be filtered on. They can only select images with those tags.
  • If the user uploads an image, it automatically adds the first tag to that image.

This will help maintain organisation in the media gallery. e.g. all “body” images can be tagged properly even if editors are quite lax.
