blank.gif not being found

If an item in a poll has not been voted on yet blank.gif is included in polling results. For some reason blank.gif not being found when results displayed. Polling working fine except when results displayed cannot find blank.gif for not voted on items. Items voted on show horizonatl bar & %. Items not yet voted on show a missing GIF and %. I've checked and can see blank.gif in the image file under textfile. I am using version 2.02

Following is my php file....Thoughts how to resolve??

<?php
/* Include this before your html code */
include "/home/warrenmo/public_html/Poll/textfile/poll_cookie.php";
?>
<html>
