A program to concatenate multiple images into one

Call it from the command line and pass it n parameters, the first n-1 parameters
are the names of the images from which you wanna create another image and the n-th
parameter is the name of the final, concatenated image

example: ./concat-images.rb rodrigo.png bia.png brothers.png

will create a file named brothers.png that contains all other images passed to the program

but before you can use this code like above, you should tell chmod to let this program run:

chmod +x concat-images.rb

Enjoy this code!

=end

require "rmagick"
include Magick

def concat_images(*images)
  images_files = images[0..images.length - 2];
  file_name = images.last

  image_final = Magick::ImageList.new(*images_files)
  result = image_final.montage
  result.write file_name
end

concat_images(*ARGV)

So simple, really looks good. 👍
