Hiall, Call me stupid if you like .,) but it seems i can''t figure out how to get a named link using a combination of link_to and image_tag.

Why is RJS so dependant on programatic creation of Javascript? RHTML is a great implementation in that it puts HTML first, and Ruby second. I would have thought RJS would be the same way: a .js with ERb helpers for generating Javascript functions. RJS putting Javascript second means: - I have to learn a whole new set of commands to use Scriptaculous. - Developers have to constantly chase the
