A nice little FREE widget that takes a snapshot each time you click its shutter. (It puts the image of a camera on your desktop when you open the widgets.)

You can do the same thing by making a movie in iMovie and then saving frames, but this is much faster and simpler.

I took a dozen snaps that were immediately saved to the desktop as .jpg files. Haven't tried resetting for a different save location nor different file type, as .jpg and the desktop are what I would select anyways.

The cons I found were: 1. No viewer! You guess at where your iSight is pointing and hope you get the shot you want. 2. Documentation? The simple operation doesn't really need any, but I know some people who need a step by step tutorial to click a mouse button. 3. A few snaps on the desktop are fine, but if you wanted to keep snapping at that UFO the desktop would be buried very quickly. Setting a default folder might work better.

Tested with PowerBook 1.6Gig/OS 10.4/iSight
