1. Again you need to make sure the photo isn't too big as in step #1 above.
2. Click the "Post Reply Button" at the bottom of the appropriate thread.
3. A window pops up to reply to the thread. You'll see the box that you type in called "Your Reply". Below that box is one called "Attach File" with a "Browse..." button. Click on the "Browse..." button and locate the photo on your computer that you want to attach. The name & location should show up in the little window.
4. After that, just click the "Submit Reply" button as with a normal post.
Good Luck ~
