This is my workaround for adding additional images to a node.

  1. I create a new temporary Page, and attach an image using Image attach.
  2. Looking at the page source code, I copy the HTML which displays the attached image.
  3. And then I paste the HTML into an existing node (ensuring that the node's Import Format is set to Full HTML (or PHP code)
  4. Finally, I delete the temporary Page I originally created (or ensure it is unpublished, if I intend to use it again)

The downside is that the additional image(s) do not appear as thumbnails in the Attached Images section, but they do appear in the pull-down of available images.
