Import a image into a content type of News item with collective.transmogrifier

I'm doing a migration to Plone 4 with collective.transmogrifier some data from an ASP Web page with MS SQLServer, specifically required to migrate certain pages that have an outstanding image.

The outstanding image is stored in the file system and in the table of the database file name it is stored only as reference. The rest of the data are exported in CSV format.

These data should be stored in the News item content type, I mean I have to charge the outstanding image within the field "Image" but I do not quite understand how to import data from CSV file and when defining values type of content perform loading image from the file system to the field "image".

Any idea?

If all the data is available on the asp web pages then why not use funnelweb?
