Answer 1

 require "open-uri"  open("your-url") {|f|    File.open("whatever_file.jpg","wb") do |file|      file.puts f.read    end }   

Answer 2

Try using the Mechanize gem:

Start with: gem install mechanize to install Mechanize.

Then:

require 'rubygems' require 'mechanize'  agent = Mechanize.new link = 'http://www.asite.com/pic.jpg' agent.get(link).save "images/pic.jpg"  

EDIT: To make things cleaner I would suggest you use the File's name itself when you save the image. I had an issue saving bulk images because they were not formated correctly. The images were saved like this:

#pic.jpg(1) #pic.jpg(2) #etc. 

Thats why you should probably use the image name as the file name like this:

agent.get(src).save "images/#{File.basename(url)}" 

File.basename takes the image url and just returns the the actual image name:

File.basename("http://www.asite.com/pic.jpg") # returns the image name pic.jpg
