You know, the button when lets you show pictures from somewhere else onto here? Either I did it wrong or I don't know, but none of my pictures are showing, they appear as a box with a Red 'x' In it and I'm wondering, is it a bug or me just doing a bad job of making it appear? Cause I'm pretty sure I did it right...I think...

This means that you're putting the wrong image url. This button does nothing except adding <img> tag with src attribute that you're putting in the popup box. Of course, HTML tags can't be bugged, so the problem is in url.
