        // Note: the "b" in "wb" in the open method may not be needed in
// non-Windows environments.  In Windows it indicates that you're writing
// binary information.  You probably won't need it for downloading straight text
// or html either.

require 'net/http'

Net::HTTP.start("static.flickr.com") { |http|
  resp = http.get("/92/218926700_ecedc5fef7_o.jpg")
  open("fun.jpg", "wb") { |file|
    file.write(resp.body)
   }
}
puts "Yay!!"

Note that this will *not* follow redirection by default. See http://www.ensta.fr/~diam/ruby/online/ruby-doc-stdlib/libdoc/net/http/rdoc/index.html

If you want to download images from web pege, you can use ruby gem image_downloader

 
require 'rubygems'
require 'image_downloader'

downloader = ImageDownloader::Process.new('www.test.com','img_dir/')
downloader.parse(:any_looks_like_image => true)
downloader.download()

or use open uri


    def download full_url, to_here
      require 'open-uri'
      writeOut = open(to_here, "wb")
      writeOut.write(open(full_url).read)
      writeOut.close
    end
