I have a URL to a image which i want to save. I looked into ruby file handling and did not come across anything. Please guide me towards some links or blogs which talk about the same. I need to then use Paperclip to produce a thumbnail of this image to be used in my application.

Check out Net::HTTP in the standard library. The documentation provides several examples on how to download documents using HTTP.

Try this:
require 'open-uri'
open('image.png', 'wb') do |file|
f << open('http://example.com/image.png').read
end

This works. Thanks. I tried this on an image. The image was not properly written to the file. As if it has been corrupted or something. Also could you guide me to do this same in a Rails application. Can i use this in a Rails application ?

Yes, you can use it in a rails application. The file not being written properly is probably because I forgot to open the destination in write-binary mode. I'll edit that now.
