can i install snipping tool in windows xp

The Windows 7 Snipping Tool is not available for XP.

To make screenshots:

1. Press the Print Screen key on your keyboard
2. Open a photo editor and paste the screenshot. Paint is included with Windows if you don't have a photo editor.

These are some tools that works with XP. A lot less cumbersome than what XP has built in. There are others out there if you search.

If so, where do I find the download?

I use the free vesion of Super Screen Capture with my Windows XP, SP3 and I love it.  One drawback I've found is that it only works on my primary monitor.  If I want to capture something from my second monitor, I first drag the window over and then do the capture.  If has a multitude of options, but I only use the rectangle tool to capture a portion of the screen.  The other drawback is that it inserts www . zealsoft . com (without the spaces) into the upper left of the capture.  Since I'm using it for a partial screen capture, I simply start my rectangle a little further up than what I need so I can crop it to size without the advertisement in it.

What I do like is that it does not chat with nor post my screenshots on the internet. I don't know anything about the two that Bruce Hagen listed, but I am familar with one called Jing which is designed to put every screenshot on the net.  That's fine if that's what the user wants, but I prefer to keep my pictures to myself.
