Here's a quick-and-dirty solution, it isn't pretty but it should 
get you going (display is a part of ImageMagick):

#!/usr/bin/env ruby

Dir["*.jpg"].sort.each do |file|
  Thread.start do
      `display #{file}`
  end
 puts "Enter caption for #{file}:"
 caption = gets
 if caption && caption!="\n" then
  File.open(File.basename(file,".jpg")+".txt","w") do |file|
   file.puts caption
  end
 end
end
