How do you stop the beeping sound when you press the menu biuttons etc e.g. like to view your pictures etc on the SONY Cyber-shot DSC-W350 ? it is really annoying to hear the beeping every time you flick through your previously taken photos...

I have a W560, but maybe it's the same on your camera. It was driving me insane as well. On my camera, I went to the menu, under Main Settings there was something called "Beep." It gave the options of "Shutter, High, Low, and Off." If I chose Shutter, then it keeps a shutter-like noise when you take a picture but turns off the annoying beep whenever you push any other button. I assume if you choose Off it will turn off all noises.

Hope that helps!
