I think you are trying to print the output from your BioPerl script to the STDIO. Instead of printing your output on the terminal / html page, try to print image to a file name defined using STDOUT or forward output file to a .png file.

use something like

perl create_image.pl > foo.png

Now use the file name of image (foo.png) with in your html page. For example:

<img src="foo.png" alt="foo here" />

Rajesh, you can actually create the HTML and PNG in one go, as one HTML file, by embedding the PNG image in the HTML itself, which I think you may be interested in. The details can be found in the, for example, this StackOverflow question, and it basically comes down to a carefully crafted [?] element. Something like this answer:

<img alt="My Image" src="data:image/png;base64,iVBORwA<MoreBase64SringHere>" />

I understood it does not necessarily work in all browsers.
