Ypu can't use the quick reply box. Go to "advanced" and scroll down. In the second box down there will be a button that says "manage attachments." Click on that. On the screen that comes up, at the top left there are 5 buttons that say "choose file." Click on one and choose the picture you want to post. Scroll over to the right and there is a button that says "upload." Click that and it will attach the pictures to the post. Scroll all the way down to the center bottom and click "close this window." Make sure your pictures are less than 2 megabytes. (The software lies when it says "up to 5 meg."
