module RailsConnector
# This module contains helpers that can be used to reference images and other assets stored in the CMS.
#
# Use this helper to take advantage of rails' asset host mechanism.
# (See http://api.rubyonrails.com/classes/ActionView/Helpers/AssetTagHelper.html for details about asset hosts.)
# If your application does not use any asset hosts, the helper will generate regular (=non asset host) pathes.
module CmsAssetHelper
# Returns an html image tag for an image stored in the CMS.
#
# +target+ is the image from the cms to be referenced in the image tag.
# +target+ can be an +Obj+ or a +Link+ or a +LinkList+.
# +options+ can be used to specify additional html attributes for the tag.
# If you do not specify an html alt attribute, the helper method will use
# +target+'s +display_title+ as the html alt attribute.
# If your application is configured to use asset hosts, the images tag will reference
# the image using one of your asset hosts.

# the object using one of your asset hosts.
