How do you use your laptop webcam for a dell inspiron 1520?

Hi! it depends on what you want to use it for, The dell web cam folder found under the start / All Programs will get you started. The web cam can be used for web broadcast, recording yourself to send to someone else, or to link live via a client like Windows messenger live. Some versions can be set up to monitor a room and activate by sensing motion in the cameras scan area.
The programs listed in the Dell web cam folder are
Dell web cam center - by creative technologies, for capturing pictures video etc.
Dell web cam manager - start a video chat (clients are listed) create an Avatar
Dell web cam console - set the brightness, contrast color, effects etc.
The best way to find out is to try, its fun and you can only learn......
