Chris@909: # == Using plugin assets for form tag helpers
Chris@909: #
Chris@909: # It's as easy to use plugin images for image_submit_tag using Engines as it is for image_tag:
Chris@909: #
Chris@909: #   <%= image_submit_tag "my_face", :plugin => "my_plugin" %>

Chris@909: # This module enhances one of the methods from ActionView::Helpers::FormTagHelper:
Chris@909: #
Chris@909: #  * image_submit_tag
Chris@909: #
Chris@909: # This method now accepts the key/value pair <tt>:plugin => "plugin_name"</tt>,
Chris@909: # which can be used to specify the originating plugin for any assets.
