A single image file that can be attached to a catalogue item, most commonly a product through ProductImage. The bytes are not held on the row, only the hash of the stored file, so showing the image means reading that hash from the blob store. The ordinal orders the images within the item, so an item's gallery and its main image are decided by ordinal rather than by insertion order. Deleting the owning ProductImage deletes the ItemImage with it.

| ordinal | Integer | Position of this image within the item's images, used to order a gallery and to pick the main image. Null if no position has been set, so check for null before comparing. |
