Uploading files using FileColumn

Hi Guys,             My end result should be to upload doc's and pdf's. I've got file_column (http://www.kanthak.net/opensource/file_column/) working for uploading files. However when I want to view them I get the following problems.

<%= image_tag url_for_file_column("career", "cv_path") %> it redirects to the following URL src="/career/cv_path/development/8/Ceylon_Synthetic_Textile_Mills.doc?1167117912" where career = model, cv_path = field, 8 = career_id when it should be without the "development" Does anyone know how I can change this?

Also how do I get it to to display doc and text files as well. Thanks.
