I would like know how do I display images that are stored on a file store outside the public folder. I will be creating these images outside the web application but wanted to display the images. What are the options available for me. I looked at the file_column and the fleximage plugins. I could not figure it out. Could someone help me out. Thanks sm

Thanks for the replies. I wanted to store the actual images in the file store outside the public folder. But have references to these images in the database. I will be pre-rendering these images in different formats. Basically I wanted to traverse an hierarchical tree menu and at the end of the leaf when further branches are not there, I wanted to display these images as thumbnails. When clicked on the thumbnail, I would like to show the actual image. Also wanted to implements the REST style routing.

controller

def index     menu= Menu.find(params[:menu_id])     @catalogues = Catalogue.find(:all, :conditions => "parent_id='#{menu.id}'")     if @catalogues ==       @contents= Catalogue.find_content_for_the_catalogue(menu.id)     end     respond_to do |format|       format.html # index.rhtml       format.xml { render :xml => @catalogues.to_xml }     end   end
