I have seen sites where a camera on a location, feeds live images to the site...the pictures are then updated periodically, lets say every 5 mins.
Could you please tell me how this is done.
Many thanks

I don't mean to be a snip but: If you have to ask how this is done, then you're probably not ready to do it.

Now, I don't know if you want to do it, or are just curious, but I'll tell you what I know. It could actually be done several ways, but the basic idea is this: The camera takes a new picture every few min. and uploads it to the web server, and replaces (in effect) the earlier image.

You could do this manually yourself, take the picture, save it as a gif, connect to your internet service, upload the picture, etc. Obviously this would be very labor intensive. People who do this automate the whole task with the following: 1) they have a dedicated internet connection (no dialing, no modem, just always connected), 2) the camera takes digital pics, and saves/uploads them automatically, 3) the server runs a program (probably a CGI script) that looks for new pictures, and displays them/updates the HTML in the page as they come up (probably leaving the old pictures so you could conceivably view several in sequence if you wanted).

You could also do this w/some streaming video programs that are out there, but again that involves a special camera, a fast connection, and full access to you server (to be able to run the streaming software).

For more specific information information you should probably go to a site that does this, and either ask them or check for links relating to how they do it (they might tell you right on the site, people are always proud of such technological feats, and usually want to tell you how they did it).
