button_to_function with image?

I couldn't find a way to pass an image as parameter, but you can
fabricate it yourself.

  <%= content_tag(:button, image_tag("ok.png")+"Submit", :type => "submit") %>

A good candidate for a helper.

Mike,

   > But here's what I did:
   > <%= content_tag(:button, image_tag("btn_send.gif"), :type =>
"submit", :onclick => "closeiframe();") %>
   > So when I do this, it puts a button-box around "image_tag".

Yep. That's what you're looking for, arent't you?

Note: if you don't need text in the button, there is :
   image_submit_tag
