hi, i am developing a few related web sites (umbraco 13).

Each of these sites has its own 'private' local file system where its media files are stored.

I would like to create a 'read-only' media folder with content that will be available to all sites (in addition to the normal private media files).

So, for example, when a media picker editor is opened for file selection, it will display the 'standard ' available files and also a folder that when open will display the shared stuff.

Any ideas?
