To answer your question, we don't have high level support for image linking, but we do have support close to the PDF level.

So, you'd have to do something pretty terrible like this in the current Prawn release (0.14.0):

require "prawn"
require "open-uri"

Prawn::Document.generate("x.pdf") do
  image(open("http://prawn.majesticseacreature.com/images/example_pdf.png"), 
        :width => 300, :height => 300)
  link_annotation([bounds.absolute_left, 
                  bounds.absolute_top - 300, 
                  bounds.absolute_left + 300, bounds.absolute_top], 
                      :Border => [0,0,0], 
                      :A => { :Type => :Action, :S => :URI, 
                        :URI =>
                            PDF::Core::LiteralString.new("http://prawn.majesticseacreature.com") } )

end

Obviously, we'd be interested in a patch that would implement this feature at a higher level. Prawn has a lot of half-done stuff in it because the project went mostly inactive for a couple years, but we're now actively working on it again and welcome contributions!
