Here are some photos of a table I made out of Santos Mahagony, Spalted Maple, Andes Cherry (legs) and Wenge inlays. Photo stuff is not my forte so please bear with me. (Each time I've tried to upload the file (jpeg) I get a page cannot be displayed message)
Did you tell it which file on your computer to upload?
After you select jpeg picture, click on the "Browse" button and navigate to the folder (directory) where your picture is stored. Highlight the picture you want to upload, and click on the "Open" button. That takes you back to the upload window, so click on the "Upload File" button. You will get a message that tells you the url of the uploaded file. Highlight the complete url, copy it (Ctrl+C), then paste (Ctrl+V) it into your message where you want the picture to appear.
