erb image link

I have an HTML image tag, but how do I wrap it in a rails erb link_to
element?

  <img src="/images/index_promo_long.png" alt="Promo Image" /> <- how
do I link this with link_to

image
<%= image_tag("/images/blah/blah", :alt => “Promo Image”) %>

link_to_image
<%= link_to(image_tag("/images/blah/blah", :alt => “Promo Image”), stuff to build link) %>

Have you tried the following? I would also check out link_image_to().

link_to(image_tag("/images/index_promo_long.png", :alt => "Promo
Image"), "http://www.example.com")

or

link_image_to("/images/index_promo_long.png", "http://
www.example.com", :alt => "Promo Image")

The first form is correct. The second form is deprecated.
