Don't use file column, use Rick Olsons acts_as_attachment. Much more used, and therefore much better tested, and it's just better in the first place imo.

Has anyone had any experience of migrating to acts_as_attachment from file_column with an existing project? I have hundreds of images all neatly resized into various folders and would need to keep them all where they are.
I'm not averse to rewriting a little code, just not my entire application!
