I have a lot of epubs with a crap file '*.png" and external links often dead that I'd like to remove (twitter,...) on a large selection.
Is there a way to clean these epubs by entering filename criteria and selecting clean external links.

I know how to do it manually for the image, book after book.
1) edit book
2) report -> list of images
3) delete of the image
4) calibre repair function for dead reference
