Webcam support in Linux is a joke you have the ability to take a snapshot but no basic control over the camera i.e. brightness, saturation, gamma or exposure.
Unless your webcam has automatic colour adjustments you'll basically end up with extremely dark and disappointing images.
Anyway in terms of software you're need fswebcam to capture your image, apache to serve it as a photo in a webpage and a bash script called via crontab to keep running fswebcam.
