And if I'm such a noob I hadn't known that, how am I supposed to make sure everyone else has it in their cache, too, so they can see the picture, based on your little "hint"?

Hahahahaha!!!

This post proves beyond a doubt that you are either a bigger fucking idiot than I ever realized, or you simply didn't read Fink's post. Or maybe we're working with a language gap here. He explained in detail what you had to do to see if your images are working or not. I was actually shocked myself to see him nicely and politely trying to help you, and extremely amused that you responded to his effort with hostility.

You CAN'T make sure it is in everyone elses caches. What you can do, and what Fink explained how to do, is figure out if the only reason you are seeing it is because it is in YOUR cache. If hot linking isn't allowed for an image, and the host is going through an effort to keep it from being hot linked, then you just need to find that image in another location or resolve to use another image.
