UPDATE: lossless image size reduction of whole folders

smushit.com reduces image sizes dramatically, lossless!
Great for logos/icons…, but does not work for gifs!

I put together a small script to automate smushing (as long as i cannot find a popper API).

Usage
ruby smush.rb http://my.file.com/123.png where/to/save.png

Install
requires ruby and rubygems

sudo gem install json

Store this into smush.rb

optional(if this task is to full/gets blocked):
cange the &task=89266837334214400 to something else or use random

#smush.rb
def store_smushed_image(url,file)
  File.open(file,'w') do |f|
    f.puts smushed_image_data_for(url)
  end
end

def smushed_image_data_for(url)
  require 'cgi'
  url = CGI.escape url
  
  require 'net/http'
  require 'rubygems'
  require 'json'
  
  http = Net::HTTP.new('smushit.com')
  path = "/ws.php?img=#{url}&task=89266837334214400&id=paste2"
  
  resp, data = http.get(path, nil)
  raise "oops #{resp}" unless resp.is_a? Net::HTTPOK
  
  path = "/#{JSON.parse(data)['dest']}"
  resp, data = http.get(path, nil)
  data
end
