Script to download a Flickr photoset.

fliwn.rb

#!/usr/bin/env ruby -wKU

require 'rubygems'
require 'flickraw'
require 'open-uri'
require 'fileutils'

FlickRaw.api_key = "YOUR_API_KEY"
FlickRaw.shared_secret = "YOUR_SHARED_SECRET"

photoset = ARGV.first || raise(ArgumentError, "Missing photoset")

photos = flickr.photosets.getPhotos(:photoset_id => photoset).photo
total_count = photos.size
photo_count = 0

FileUtils.mkpath(photoset)
photos.each do |photo|
  photo_count += 1
  puts "=> Photo #{photo_count}/#{total_count}"
  puts "   #{photo.id} #{photo.title}"

  puts "   Getting info"
  info  = flickr.photos.getInfo(:photo_id => photo.id, :secret => photo.secret)
  url   = FlickRaw.url_o(info)
  name  = File.basename(url)

  next if File.exist?("#{photoset}/#{name}")

  puts "   Downloading #{url}"
  File.open("#{photoset}/#{name}", "wb+") { |f| f.write(open(url).read) }

  puts "   Saved #{photoset}/#{name}"
end

Thanks!
