When you click on post reply at the bottom of the page, it will take you to the reply page. At the top of the text box, there is a paperclip, this is for the attachments. Click on it and it will open a new page. Click browse in the new page and then choose the pic from a file on your computer. Then click upload pic and give it a minute. Or if they are on another web page already, you can copy and paste. Good luck.
