Known WebCam ProblemsThe WebCam keeps reloading the same image with the same time/date stamp. Why? The most likely reason for this is that there is a break in communication between the WebCam and the Internet. The page will continue to reload the last image received by the server until communications are restored. Hit reload (refresh). If that does not work come back to visit later. The WebCam shows a white page or a partially loaded page and then quits. What should I do? This is a good time to hit the reload (refresh) button to start the WebCam images reloading again. If that doesn't work, try visiting again later. When I come back to the WebCam after being away, it shows an old picture. Why? Your browser didn't update the photo because it was not the active window. When you first come back to a WebCam after being away, hit the reload (refresh) button to see the latest image. That will get the ball rolling once again. The WebCam page loads but there is no picture, Why? If you are getting a gray or black rectangle instead of a picture it means that you are not visiting during daylight hours. There are no artificial lights in front of the WebCams. Problems with Netscape Navigator There has been a long-standing problem with Netscape Navigator (Communicator) that seems to have been resolved by Netscape somewhere around Communicator version 4.03 and Navigator version 4.2.115. Earlier versions displayed the following misbehavior. Despite the fact that there is an html tag on the WebCam page that tells your browser not to cache the image, some versions of Netscape Navigator reload the image a few times (sometimes several times) and then cache it. Once it is in your cache, the cached image is called up instead of the image on the NPS server. The result is that you keep getting the same image with the same time-stamp on it. If you are using Navigator or Communicator, and you are experiencing difficulty, try upgrading to the latest version. Problems with Macs MS Internet Explorer version 4.01 (Power PC) and Netscape Communicator version 4.61 (MAC) both seem to run the WebCam fairly well on a PowerMac. The one problem that has been noted is that the page reloads 30 seconds after the start of the previous reload, not 30 seconds after end of the previous image reload. What this means is that if your connection to the Internet is slow and it takes more than 30 seconds for you to download the image, you may never see a complete image before the next download. If your download time takes 25 seconds, you will only have 5 seconds to view the photo before the next download. Efforts to solve these problems will continue. |
