Title shouldn't be required

The 'Title' field for image nodes could easily default to the name of the image file, which would be much easier on the user, especially in the large number of cases when the user actually wants to use the name of the file as the title, and otherwise have to go figure out the name in their local filesystem(or skip on down and choose their file before entering a title) and copy/paste or re-key it in which is a pain.

Perhaps, something like:

Title:
___________________________
Optionally specify a title. If left blank, the image's file name will be used.

This behavior would not upset current users' expectations or affect the way anyone works, it would be an invisible improvement that would increase usability and speed up workflow.
