Website for proper form? Weigh lifting question

I've been lifting for about a month now, and although I'm doing my best to lift properly, my basis for comparison is a series of 1 inch animated GIFs off a workout site, plus some vague memories from my high school weights program (that was a looong time ago).

Is there a web site that has more detailed guides on the proper form for basic exercises?

Ideally I'd find a personal trainer to walk me through a session or two, but a website would be ideal. Details on how to do a proper dead lift, squat, bench press, etc. would be a life-saver.
