The Old Faithful streaming webcam came back. At the left are the latest image from the old still camera, and below it is a snapshot from the new camera. That still image can become a live image by clicking on the green button at the bottom right of the image. Clicking on the red button will stop the stream. Clicking anywhere else on the image will take you to a full webcam image page where you can do other things. The black button turns on the audio commentary stream. The blue button will zoom the image to full screen. Clicking on the still image will zoom it to full size. The status bar from that image is also being displayed at the bottom of the streaming image.
Displaying real-time images like this is CPU intensive, and I decided that on the front page it was better for visitors to this site to have the option of turning off the stream, as the only other alternative was to close the page. And driving people away from my webpages seems counter-productive.
If anyone wants to add similar support for this webcamera (or others) using Silverlight, please don't just steal my work. You are welcome to contact me for help, advice or even a copy of the code.
