Alice...when you create or respond to a post, beneath the message area there is a paper clip with the words "Insert an Image File" next to it. Click on that paper clip and a text box will open, allowing you to upload a photo (up to 90kb, up to 2 pictures in a post) to your post. This does not work with the quick reply space at the bottom, but only if you click on "Reply to this message". Hope this helps.
