Jen,

Unless there is a particular reason (e.g. dynamically created images),
why are you reading image files directly in Perl, then dumping the
output? You should just use CGI to generate HTML that looks like this:

<img src="/images/some/path.gif"/>

Even if you want to dynamically *choose* the image, you are better off
having CGI/JSP/etc. dynamically fill in the src <img
src="${some_dynamic}"/> or <img src="<%= someVal %>"/> rather than
actually literally feeding the image.
