Help a worried guy out...

I was rollin through /b/ opening any images that looked like they might be of any interest. Turns out 2 of them were CP. I didn't save them or anything, but they did load. Do the authorities care? I'm on my neighbor's wifi so the ISP will call them if they have a beef, and I don't think they have a tracker or anything. Am I screwed?

No. You're probably fine. But it would be a good idea to clear your browser's cache. Also, /b/ is garbage. Stop browsing /b/.
