def image_attributes(item, image_name)
  ["/Height Units", "/Width Units", "/URL"].collect do |s|
    XPath.first(item, image_name + s).text
  end
end

["small", "medium", "large"].each do |s|
  eval %{ $#{s}_image_height, $#{s}_image_width, $#{s}_image_url = 
    image_attributes(item, "#{s.capitalize}Image") }
end
