Issue with product and image URL not being correct (especially with a non-standard installation). To fix,

FIND
$imageURL = HTTP_SERVER . DIR_WS_CATALOG . DIR_WS_IMAGES;
$productURL = HTTP_SERVER . DIR_WS_CATALOG .'/product_info.php?products_id=';
(around line 13 in yahoo.php)

REPLACE WITH
$imageURL = HTTP_CATALOG_SERVER . DIR_WS_CATALOG_IMAGES;
$productURL = HTTP_CATALOG_SERVER . DIR_WS_CATALOG .'product_info.php?products_id=';

Updated yahoo.php file attached
