Try using heredoc. Makes it a lot easier to print out HTML from within PHP.
echo <<<HTML
<td height="80">
<a title="{$result[$count]->Description}" href="productimages/{$result[$count]->ProductCode}.jpg" rel="lightbox">
<img width="75" src="productimages/{$result[$count]->ProductCode}.jpg" title="{$result[$count]->Description}" border="0" />
</a>
</td>";
HTML;
Note; You can not put any white-spaces (tabs, spaces, etc...) before or after the "HTML" delimiters, or you will get parse errors. (Except, you can add spaces between the <<< and the HTML in the first line.)
