Here's the entire IF function, going from lines 656-663, with line 659 in bold:
if(empty($tag->type) || $tag->type != 'title'){
if(!empty($product->file_path)){
$image = hikashop::get('helper.image');
[b]$result .= '<table class="acymailing_content"><tr><td valign="top" style="padding-right:5px"><a target="_blank" style="text-decoration:none;border:0" href="'.$link.'" >'.$image->display($product->file_path,false,$this->escape($product->product_name)).'</a></td><td>'.$description.'</td></tr></table>';[/b]
}else{
$result .= $description;
}
}
I just used the integrated upgrade function this morning. Running Hikashop 1.4.7 on Joomla 1.6
