Not all web traffic, just the images to check. With any decent bandwidth, it shouldn't be an issue for most. It also setup in such a way as to not cause a downtime if the checker goes down.

Oh? Would the fallback be that it simply doesn't do a check? Or perhaps it could disable image uploads if the checker is down? Something else? Presumably, this would be configurable.
Yeah, that was poor wording on my part — what I mean to say is that there would be unvetted data flowing into my local network and being processed on a local machine. It may be overparanoia, but that feels like a privacy risk.
I don't see how it's a privacy risk since you're not exposing your IP or anything. Likewise the images are already uploaded to your servers, so there's no extra privacy risk for the uploader.
For clarity, I'm not claiming that it would, with any degree of certainty, lead to incurred damage, but the ability to upload unvetted content carries some degree of risk. For there to be no risk, fedi-safety/pictrs-safety would have to be guaranteed to be absolutely 100% free of any possible exploit, as well as the underlying OS (and maybe even the underlying hardware), which seems like an impossible claim to make, but perhaps I'm missing something important.
You mean an exploit payload embedded in an image, and pwning a system parsing that image through python PIL? While there's never a 100% chance of anything, you're more likely to be struck by lightning than this coming to pass and at that point you're at more security risk at using the internet altogether.
