Go to "Switch to full Reply Screen", then click on "File Manager" and it opens another window. Click "browse" to find your picture on your computer. Then click "Add File" and then "Done adding files", which closes the small window and brings you back to the posting form. Click submit and your picture should be there. If it is too big it will show as an attachment. Here's your picture, the way I sent it to you this morning, after I resized it. Give it another try!
