Auto Reload is a Blender addon designed to help with external Images and Libraries reloading.
It allows user to inspect these external files, open, rename, delete them from convenient Panels in the Scene Properties.
User can also launch a Timer (located in the Top Bar Menu) which will retrieve automatically modified Images every n seconds, and will fetch Libraries for modification.
