I'm gonna go on a limb here and say it's because you are using a static IP address rather than a dynamic one. In the properties of your pic, it lists exact numbers for the beginning of the webpage. Is there an actual address that you can use? Something like
http://www.yahoo.com instead of
http://192.36.57.0? From the numbers, it's looking more and more like you have it saved on your network somewhere and it is giving you the numbers as a sort of shorthand to reference to your pic. That's why I was suggesting that if you could get to your webpage without using your tools (getting their like we would) that it would give you the right address for you to use. Memnoch has offered to give you space on his website to host your pic. We know that his signature works, so you may want to go that route til you can get yours stable. Good luck with it whatever you do though.
