Subject: Newbie - Test For JPEG Image Over HTTP

Hi

I would like to test for the existence of a .jpg image on a remote 
server over HTTP.

I have tried 2 different methods but they are not what I need.

Method 1:

require 'open-uri'
if open('http://example.net/path/to/image.jpg')
   # do something
end

Method 2:

require 'net/http'
if Net::HTTP.get 'example.net', '/path/to/image.jpg'
   # do something
end

The server where the images are always returns a default page if the 
images do not exist so the code above always returns.

What I need is a way to check what is returned is not a html page but is 
a .jpg image.

Any help greatly appeciated.
Thanks
Neil
