Looks like MSN may have changed their policies. I have posted photos out of there before here and it worked fine, I just tried a new one and got nuthin.
You are going to need to find a new webhost for your picture (which I was at least able to view by joining your MSN group BTW).
Edit...looks like Imageshack is the way to go, I even uploaded it for you...
