Yes it does. I'm the author so I should know ;)

Here is a webfetcher script for downloading the cover image:

  require 'webfetcher'

  url = 'http://www.amazon.com/exec/obidos/ASIN/0201708426/'
  im = WebFetcher::Page.url(url).images.find {|i| i.url['MZ']}.save('cov.jpg')

If you want to try the module you can get the latest version (0.5.3)
here:

    http://www.acc.umu.se/~r2d2/programming/ruby/webfetcher/

The RAA entry is not completely up to date. I will fix it as soon as I
can remember my passphrase. ;)
