I hope I can explain this well enough... I was attempting to make a map that displays just a normal picture when all is ok but has a warning sign when there is a problem. I set the graphics and selected X Overlay for the warning signs. In Map Maker it looks just like this.

Now that's just what I want... the one on the left is broken, the one on the right is fine. But when I view it from the webpage, I see this:

Am I doing something wrong? Or am I just trying to do something that isn't possible? Thanks in advance.
