After looking for a Unix tool that would archive webcams I gave up. None of them did what I wanted. I wanted to beable to archive the images, create thumbnails, and view them via my web browser. What I came up with is UGrabCam.
Below you can view an example of what UGrabCam can do. I run this script out of my crontab and it creates all the html pages, thumbnails, and zipfiles on the fly.
If you have a question about UGrabCam please send me E-mail. I would like to know if anyone is using this besides me.
