Taking a picture while in There is simple to do. You just need to follow these steps:

- Make sure the There client window is selected and press ALT - PRINT SCREEN
- Open the "MSPaint" application (Start > Programs > Accessories > Paint)
- Press CTRL - V to paste the screen shot into paint and save the file

Instead of Microsoft Paint, you can use any paint program which allows Edit --> Paste. Photoshop and Paint Shop Pro both work with this.
