How to take a screenshot
Once you take a screenshot, save it on your HD , then upload it at ImageShack and wehn you see all those links to the picture on the next page, scroll down and click "Show Advanced Linking" and copy the direct link to the image that appears.
Then, press the
button , paste the copied link and press INSERT and you're done.
