Please let the options settings accept media source name or ID. - i.e. :

`{ "remote": true, "settings": [ { "name": "interchange_hero_large", "label": "Large Hero Image", "type": "image", "mediaSource": "Filesystem", "value": "assets/img/heros/hero_gallery.jpg" }, { "name": "interchange_hero_medium", "label": "Medium Hero Image", "type": "image", "mediaSource": "2", "value": "assets/img/heros/hero_gallery.jpg" }, { "name": "interchange_hero_small", "label": "Small Hero Image", "type": "image", "mediaSource": "3", "value": "assets/img/heros/hero_gallery_mobile.jpg" }

] }`
