You need to use pictures that are already on line. When you find a picture you like, right click on it. You will see a box that says "properties." you will highlight the letters and stuff in the properties section, then right click on those, and choose "copy" then come back here, click reply, and in the new empty window right click again. then you choose paste. the adress of the picture you want to post will be there. you need to type this around it
[img]here will be the adress[/img] just remember no spaces.
