The seller's response to my first accusation:

"I don't take pictures from other sellers. This is not the only type of chip like this that is available for sale."

And my followup response to that:

"Take a look at the inserts (those different colored pieces of clay around the edge of each chip). Each chip is molded with clay and the insert is slightly different and unique for each individual chip. Comparing odd little shapes on each insert it becomes obvious that you are indeed using images from other sellers auctions."
