I tried to use the Mime::Types in Ruby for my file upload. I added  
require ‘mime/types’ but it says “no such file to load”. Is it a gem or  
what? Something I should install?

Yes, or if you use Rails 2.1, you can add this to the gem section of  
your environment.rb:

config.gem “mime-types”, :lib =\> “mime/types”, :version =\> ‘\>= 1’

and then run

rake gems:install
