A little script I wrote to download images from Amazon.

amazon.rb

# Download book covers from Amazon.
# Requires asin gem.
require 'net/http'
require 'asin'
client = ASIN::Client.instance

# Images Folder
IMG_DIR = ""

# API credentials
API_KEY = ''
SECRET_KEY = ''

ASIN::Configuration.configure do |config|
  config.secret = SECRET_KEY
  config.key = API_KEY
end

if ARGV.empty?
  raise "You didn't search for anything"
end

puts "Searching for: " + ARGV[0]
items = client.search_keywords ARGV[0]

items.each_with_index do |book, i|
  count = i+1
  puts count.to_s + ". " + book.title
end

print "Select one: "
selected = STDIN.gets.chomp.to_i - 1

puts "Getting: " + items[selected].title

uri = URI.parse(items[selected].raw.LargeImage.URL)

Net::HTTP.start(uri.host, uri.port) do |http|
  resp = http.get(uri.path)
  open(IMG_DIR + items[selected].title + ".jpg", "wb") do |file|
    file.write(resp.body)
  end
end

puts "Done!"
