The kindle requires the name of the thumbnail file to be in a specific format that includes a cdetype and asin that match the metadata contained within the book.

Any unique string will do for a fake asin. calibre uses its own book uuid and the KFX Output plugin generates a random 32 character string instead.

There is a slight advantage to using the calibre uuid that I hadn't considered previously. If you convert and copy the same book to a kindle multiple times it will retain the same asin and so it will overwrite the thumbnail image, instead of creating a new one each time.
