It is possible to automate this conversion, assuming we don't have to
manually check for commas being used in other ways in the subject.
(Even then, a command-line tool could prompt for each file:

Image: yieldsign.svg
Subject: yield, sign, yield sign, street sign, traffic sign
Convert to rdf:Bag? (Y/N):

Are there a lot of images with this issue, or just a couple?
