Yes, and I think, if you already have file upload working in Rails, you know which one you should do. Maybe something like this:

form_for Painting.new, :id => 'fileupload', :html => {:multipart => true } do |f|

See if that gives you any love. Realize that on your file upload handler in Rails, you will need to determine if there are multiple files or just one, and handle them differently in either case. Default is one file per file input on your form (i.e. one per form submission), but you can't count on that if you expose the :multiple => true option as you have done.

Think of this as the working model that you must adapt from PHP to Rails. Change action to your file upload action, or just add the ID of this example form to your Rails form_for method. Then fold in the JavaScript that they use to make the preview, and you should be good. If they are doing a client-side preview, then the form handler (PHP or Rails) is completely outside of the problem, not related at all to the solution.
