We are trying to create an inhouse ID card system. What we would like
to do is to have a webcam feed displayed in a webpage and for a user
to be able to click a button to save the currently displayed feed as a
jpg (on the local pc which will be uploaded to the server).

Thanks in advance
1) write the webcam image to a file (on the webserver), using a fixed
filename.
IIRC Microsoft has an XP powertoy that can take webcam snapshots. Never
tried it though. Maybe your webcam software can do it?
2) write a simple page that refreshes itself every x seconds (look up
"meta refresh") and shows that captured image
3) on some button click, copy the current captured image to some other
file, possibly with a timestamp in the filename.
