I can't tell from the formatting whether your haml is correct, but the
reason you aren't finding image_tag from the console is probably that
you don't have the ActionView helpers included. Look up image_tag and
then include the fully-qualified module for image_tag and try again.
You might also try posting to the Haml Google Group
(http://groups.google.com/group/haml
).
Hope this helps.
