I've been requested to look at removing image upload permissions for about 10-15 of our 120 groups. This would include disallowing them to upload in the For this Page/For this Block permssions. I'm wondering what would be the best approach to take this. Can I extend upon the extending permssions groups (Read, Create, etc) and make a "Upload Image" and then add that as a permission to my Image File Controller (simular to this https://world.episerver.com/documentation/developer-guides/CMS/security/permissions-to-functions/)? Thoughts?
