I have a multisite network where the super admins will be creating the individual sites. An important role we need to enable, for compliance reasons, is to restrict "Authors" to not be able to upload media, but be able to access the media library to choose from media that is uploaded by the super admin. I have downloaded the User Role Editor plugin, which is a great plugin btw, but the only option it gives is to turn off the "upload_files" function. That takes away all ability to access the media library. No bueno.
Anyone wanna take a stab at this??
