form_image_button_helper

##How to turn this into a helper with it's own form, to hide put an image behind a POST request?

# <%= image_button_to "path_to_image/png"", _action_model_path(object), :title => "title for link" %>

 <% form_tag _action_model_path(object) do %>
          <%= image_submit_tag "path_to_image/png", :title => "title for link" %>
 <% end %>
