there is a link in the help section which tells you how to do it, but for a quick run-down, after you click on the post reply button you will see a paper clip icon just above and to the right hand side of the text box, click that then brows your images on your computer, chose the picture you want then press the upload button, once you have done that close that box and then post your rely as normal, hope that makes some kind of sense lol
