cgi file is in the cgi-bin directory...cgi-bin directory is in the public_html directory ... style.css file and the tb_pic1.png image are also in the public_html directory.

If that is the case then the paths could be written as:

<link type="text/css" rel="stylesheet" href="../style.css">

<img class="my_images" src="../tb_pic1.png">
