You can "Modify" your post or add another one. On the bottom of your post there is "Additional Options". Click on it. Brings up an "Attach" box. On the right of it there is a "Browse" button. Click on it. It brings up your hard drive files. Go to where you have stored your photos on your hard drive on double click on the file name. If you want more photos, click on the "More Attachments" next to the Browse button and repeat the process. You may have problems loading them if the files exceed a certain limit. That is another story. Email me if it happens.
