Hi, I just want to tell you, it's okay.
You don't have to use a "shutter click" sound on your digital camera or cellphone when you take a picture.
There are not mechanical doodads making that noise. It's just a sound sample.
Here, try clicking on this: --> camera shutter sound <--
Did you hear a shutter clicking? Do you think your computer just photographed you?
Actually, in this case it did. I hope you were wearing clothes.
