I've just installed Version: 1.10.2 and paid attention on XML error that Google shows for generated feed. The problem is that google_base.php class function (google_base_image_url) doesn't sanitize the image name, so filenames with space, like "file name.jpg" crashes everyhing. But it's easy to fix using rawurlencode PHP function:

$products_image_large = DIR_WS_IMAGES . rawurlencode($products_image);
