Subject: How to fetch images from web page with relative path

Hi, all

here is the code, it works when the image has a full path, but I met
some pages which only gives relative path for images. How to handle this
condition?

Thanks a lot!

def self.get_magick_img_from_url(url)
    begin
      blob =''
      img_file = nil
      Timeout::timeout(5) {
        #open web page
        img_file = open(url)
      }
      if img_file
          #read page content and store into blob
          img_file.readlines().each() do |line|
          blob << line
        end
        img_file.close()
        #fetch images here
        return Magick::Image.from_blob(blob)
      end
    rescue Timeout::Error
      puts 'Timeout in get_magick_img_from_url for url - ' + url
    rescue
      puts 'Error in get_magick_img_from_url - ' + $!
    end
    return nil
  end
