Before you begin posting in the green reply box, you need to click the box that sez "go advanced"....
Once the system shifts into advanced mode, scroll down and find the button that sez manage attachments and click it.....
A browser window will open and several boxes will appear with the browser buttons next to them... Each one represents someplace to store each picture... As you browse all your available photos, they will (one by one) list themselves in these boxes... When you've added all the neccesary pictures, click the upload button and they will load into your message....
Then click submit....yer done...
