IMO, the new prompt is not much better than the old one.  They both
assume that just by prepending "Image-" to something resembling the
prompt of "C-x d" is enough to explain what the command wants.  I see
a lot of space for confusion here, especially for non-native English
speakers.

The doc string of the command says:

  Make a thumbnail buffer for all images in DIR and display it.
  Any file matching `image-dired--file-name-regexp' is considered an
  image file.

So I don't think the analogy with Dired holds, and therefore something
like

  Show thumbnails for directory:

would be a better prompt.
