Why do people not preview images? Someday you’re going to get a real surprise when some hacker inserts a child porn pic in place of the image you were trying to display.

Because the image is in the browser cache and displays properly in the preview. In fact, the original poster will still see the correct image until s/he clears their browser cache.

The concern you raise is why I try to save the image to my own web server and hotlink to it from here when I post images.

Yes, you are right. I tested it.

Sometimes, though, I think people re-post an old image link by copying source without even re-viewing it. It could have changed.
