<%= content_for :html_head do %>
  <%= javascript_include_tag "jquery.bbcode.js" %> 
  
  <%= javascript_tag do %>
    $(function(){
      $("#web_message_content").bbcode({tag_bold:true,tag_italic:true,tag_underline:true,tag_link:true,tag_image:true,button_image:true,image_url:'/images/bbcode/'});
