Try this:

  print "Content-type: image/png\n\n"
  File.open(image_path, 'rb') do |file|
    content = file.read
  end                         # file is auto-closed here
  print content

Explicitly closing a file is *so* last-century ;)

You can use 'content = File.read(image_path)' but I'm not sure if
that's read as text or binary.

No real forum to speak of.  That's what ruby-talk is for.

Check out the Ruby Documentation Bundle (ruby-doc.org/downloads) for
some meaty documentation and a newbie's guide to the Ruby community.
Summary: ruby-talk, IRC, rubygarden.org, Wiki, RAA, RubyForge.

Cheers,
