Re: [PHP3] php & webcam trouble From: Richard Lynch (lynch <email protected>)

If the page is reloading, but not the image, you may need to have your
capture.jpg actually be a script that not only sends the image, but also
some headers first to specify expiration date/time...

If the page itself is not reloading, try making it CONTENT="20;URL=whatever.htm"

If all else fails, add a ? to the end of each URL (the page and the photo)
to make everything think it's a GET query.
