Use the rubyzip gem in order to create zipfiles on the server-side:

   require 'zip/zip'

   Zip::ZipFile.open("my.zip", Zip::ZipFile::CREATE) {
    |zipfile|
    puts zipfile.read("first.txt")
    zipfile.remove("first.txt")
   }

Add the images to the zipfile and use sendfile in the rails-application to send the files to the browser. Read the documentation on Zip::Zipfile and sendfile for the missing bits.
