Well to get a screen shot of it, press the "Print screen" button on your keyboard, then open up paint and click paste. Then you have your picture.
Now you just need to upload it to get it on the net. You can use multiple hosts. Either upload it through a FTP client (http://www.visicommedia.com/aceftp/) or upload it using just your browser by going to sites like www.uploadit.org (I use this but you can only upload jpgs..) www.boomspeed.com an such..
Once uploaded click the "image" button above where you post your message, then put in the URL of your image then click the image tab again.
