Rails - Nov 2007 - How to pin down location of views/shared directory ?

My app has a header & footer I want common to each section.
They live in app/views/shared/_header.rhtml & _footer.rhtml.
They are referenced by app/views/layouts/application.rhtml as one would
expect:
  <div id="header">
    <%= render :partial => ''shared/header'' %>
  </div>


They contain many lines like this:
<a href="/classifies/categories/vehicles"><img
src="images/vehiclesButton.jpg" alt="Vehicles"
class="rollover" /></a>


This works great from my app''s root index page. When one navigates to a
controller, e.g. myapp/classifieds/categories, the images can''t be
found. Console shows errors like this:

  ActionController::RoutingError (no route found to match
  "/classifieds/categories/images/vehiclesButton.jpg" with
{:method=>:get}):

Yet my app seems to find its stylesheets (in public/stylesheets) just
fine. How do I get Rails to find its images in public/images all the
time?

And on a related note I somehow suspect that there''s some kind of
url_to
syntax I should be using instead of a naked <a href> but it''s not
coming
to me.

Thank you.

TC

It turns out that the answer, supplied by EngineYard''s awesome
support, was that I just needed to reference the directory as ''/
images'' instead of ''images''.

Thanks for the fine article, Greg, That is one ambitious piece of work!

for images you should use <%=
image_tag(''vehiclesButton.jpg'') %> if
your image is in images directory and it will automagically match the
url where ever you are in your app. If you use something like <img
src=''someimage.jpg''> then it will have some path related
problem at
some point of time.

if you want to make your image a link then you can either use link_to
image helper or simply
<%link_to(image_tag(''vehiclesButton.jpg''), :controller
=> :controller_name, :action => :action_name)  %>

hope this helps
