LJ webcam - techno question - Kayak Fishing Adventures on Big Water’s Edge

Does anyone know how to grab a single image from the web-cam? I don't mean a screen shot, more something like this:

http://bigwatersedge.axiscam.net/axi...mjpg/image.cgi

I have a webcam application that goes out and grabs images once every 5 minutes or whatever setting you choose and saves the images. It would be cool to do that with the LJ webcam.

wait till the camera times out, then just drag it to your desktop

If you mean to do that every 5 minutes, then I'll pass - if to get the image info, I found image is named video.jpg - I added that to the cgi url, but it didn't work.

So are you trying to hit the LJ cam every 5 minutes, cache a still and render elsewhere? I might be able to help you if you provide more req's.

Close. If I can grab a still image from the LJ cam once every 5 minutes using a url link or something similar, the software will automatically save it to a file. At a later point I'll put all the images together for a timelapse video.

maybe this helps:

the webcam page source includes a file called lajollawebcam.js

http://www.bigwatersedge.com/webcam/lajollawebcam.js
the javascript auto creates the IMG tag and cycles a new image.

the IMG tag code is in there. the only hangup might be the
"theDate.getTime().toString() which will be part of the document.write code.

however, I'd guess ?? that if you worked up the code from that (see code)

baseURL+=File+= etc. you'd be able to grab the image in a browser with javascript. now, can you use it in another application? well, once you can grab them from the internet, pretty much it's a scripting issue.

in fact, any app that can grab internet images could, the only hiccup will be the getTime() issue and filenames.

hope that helps.
