You can print either HTML or an image. If you mix it, it will fail miserably.

You say you want to print an image, so do that - but don't print HTML also (you use start_html and end_html)

You're also printing two headers, remove the first one (only print the image header, not the HTML one).

If you want to print both an image and HTML, split the script up into two scripts - one that emits the HTML which contains an <img src="http://url.to/other/perl/script.pl"> that points to the second script.
