How do you screen scrape an image off of a web page?

How do you screen scrape an image off of a web page?

You find the URL of the image (possibly resolving a relative URL
against the absolute URL of the page) and then ask the web server to
send you that file over http.

I suspect Sean is asking, what's the ruby way of doing a wget?

For example:

wget http://www.ruby-lang.org/images/logo.gif

Here's a script I found at http://www.rubynoob.com/articles/2006/8/21/how-to-download-files-with-a-ruby-script

require 'net/http'

Net::HTTP.start("static.flickr.com") { |http|
resp = http.get("/92/218926700_ecedc5fef7_o.jpg")
open("fun.jpg", "wb") { |file|
file.write(resp.body)
}
}

Or maybe shorter:

require 'open-uri'

open('image.jpg', 'wb') {|f| f << open('
http://www.domain.com/image.jpg').read }
