I've seen pictures on Amazon being completely mismatched to the product descriptions quite a few times. Does that happen due to the database having an error and linking to the wrong files or does the seller get confused and uploaded the wrong files?
They also often change the actual product - e.g. have something good, it gets a lot of good reviews, now they switch it for some junk they want to sell. Amazon's system is stupid, it doesn't wipe out the reviews and most people only see the number of 5 star reviews, not that they are for a completely different/irrelevant product ...
It is an old seller trick.
