Ohne Bilder Upload kommt Fehler

[hammer2005]

Erstmal habe ich folgende Fehlermeldung in meinen Bildereinstellungen:
Warning: constant() [function.constant]: Couldn't find constant PRODUCT_IMAGE_THUMBNAIL_//DROP_SHADDOW_TITLE in /is/htdocs/wp1018320_PFBC93RJ1C/www/shop/admin/configuration.php on line 142

Und dann habe ich noch diese wenn ich kein Bild hochlade bei einem Produkt:
