(just speaking for Ethereum) The gas fees are a constant, so you pay a certain amount of ETH to mint your NFT. You don't upload any image data but solely the address (so a couple of bytes) of the owner. The reason that this costs so much is the exponential increase in ETH prices in the recent years and the network congestions (gas price depends on the workload of the ETH network). What used to be a couple of cents or so is now easily $70, depending on the ETH price and network congestion.
