Actually, it should be File:Blank icon.png because that's the image the explorer uses for objects with a class that doesn't have an explorer image index specified in the ReflectionMetadata.xml file. (Try, for example, inserting a object in ROBLOX Studio.)

However,, , and are structural classes and they can't actually appear in the explorer, so they don't have an icon at all. Classes that can actually be instantiated and shown in the explorer but that don't have an explorer image index (there should be very few) can be added manually to Module:Class icon (I just added ).
