When you are posting, click the first button under the word color, a picture of mountain and a sun. It'll ask you to enter the URL for an image. Do so and you will see the image.
If your picture would stretch the page, you can post a link to the image instead. Do this by clicking the button with a picture of the world and a chain link. Enter the image URL, then if you so choose you can type in something the user will see instead of the image URL.
This has nothing to do with TCG Questions... but LOL! I thought this was quite funny. Yeh, it's been answered, it's been tested and it works. I'll lock it incase it gets out of hand but there really isnt any reason to reply here anymore anyway...
