When you are typing in your post, under the big text box there is a link that states "Additional Options". Click that link and an "Attach" text box opens up. From there, click the browse button to get the photo from your computer. Alternatively, you can use the image tags to post an image. There are two rows of buttons above where you type in your message (above the smiley faces). The image button is the second button from the left on the second row of buttons. Put the html link in between the bracketed image tags - should look like (img)link goes here(/img).
