Subject: Re: Newb CGI Question

I just ran up a similar example using a jpeg I had to hand (yes, it
really was called 'foo.jpeg'!).

require 'cgicroak'

CGI.croak do |cgi|
    print(cgi.header('type' => 'image/jpeg'))
    print(File.read('foo.jpeg'))
end

It works, and displays the image, so the code seems all right.  Do
check things like file permissions, though - it could be that it is
failing to read the image from disk.  And, of course, check the image
itself.
