What webcam software do you use to send your webcam image to WU currently? It's usually as simple as going into that software program and getting your URL code, and then going into your webcams on your weather underground page and editing your current webcam from FTP to URL. For example, I use YAWCAM software, and in that software there is a tab that gives me my webcam URL, both a still image URL and a live streaming URL. Obviously for WU reasons you need to use the static image URL. Follow the setup directions on that WU page and then they will have to 're-approve' the image, and you should be good to go thereafter.
