As the title states, the $propertyTypes array is missing GalleryURL in the Trading\Types\PictureDetailsType class. It's present in MerchantData\Types\PictureDetailsType's $propertyTypes array (and is the only difference between the two). I've added it manually to test, and it's populated in the response of a GetMyeBaySelling request.
