The idea behind the module belongs to a customer who was willing to take full control over the Sitecore Media Library in their multi site solution. Managing more than 15 sites on one instance, it is important to restrict permissions on different areas of the content tree, as well as /media library branch.
I’ve seen too many situations in my practice where this important aspect has been neglected and hundreds of media files ended up in the root of media library, causing all sorts of performance and compatibility issues.
This module will hopefully provide a good starting point for what you can do in terms of policing your Media Library.
Instead of writing a bunch of boring docs, I decided to put a boring video on YouTube.
