Still learning, but seems like:

1) can’t be prevented at this stage

2) will compete for block space and fees like every other transaction

3) capped at 4mb / block regardless

With this in mind, I view it as mostly harmless and the market will decide if images are worthy of spending sats. I doubt it will take off to the level of NFTs on ETH/SOL given those were major grifts with worthless tokens and BTC is actually worth holding onto.
