Using file_column data in IMG tag

When I use file_column to upload an image, it seems that the correct
filename is saved in the database. But, when building a page from a
record that
contains links to the image, I get the following url when I try to use
the :image attribute in an IMG tag:

./script/…/config/…/public/picture/image/1/FOW0038.jpg

I don’t know where all of the stuff before “public” is coming from (the
rest of the path is fine). Does anyone have any insight?
