Naming external files associated with a container.
I need to find an easy way of naming files in a container. If image files are pasted into container field they are uploaded to the server location (using external storage) with names such as Untitled 1, Untitled 2 etc. Same with scanning an image into a container field. That won't do. I am sure there are expensive plug-ins available for file manipulation but is there any other way that might be triggered by the pasting of an image in a container field.
