If you find these pictures distressing, you might want to consider consciously and carefully exposing yourself to more of the same to build a minimal amount of tolerance. I’m pretty sure it’s literally impossible to go through life without experiencing (sometimes personally) medical conditions that are significantly more visually unpleasant. I’m not a huge fan of the meat-creature-universe we all rolled, but it literally is what it is.

Yes; that's my point. Is there a way of making the internet better, such that this can be handled more seamlessly, so that the people impacted by things that others find mild can just...avoid it?

Not all internet has a landing page where someone can post a "trigger warning" (for lack of a better term). Nor should it: trigger warnings don't work, and may even be harmful.

It's a dogs nose with a scab on it lol
