There is a button under the font and sizing. The "world" with a "link" allows you to enter a link to the page where the pictures are loaded (Imageshack, photobucket, car domain). The button that is yellow with "mountains" allows you add the image itself, not the link to the page.

The images must be hosted somewhere on the web, not on your personal PC.

Photobucket is free, and you can "insert Image" and paste it into the forum, and the picture shows up.
