How to post photos
At the bottom of your Reply message box you will see Post Quick Reply and Go Advanced.
Click on Go Advanced.
At the top of the message box are icons. Click on the paper clip.
That brings up a box to post up to four photos.
Click on Browse and find the pictures. I find it easiest to place them on my desktop so I can easily locate them. Click Open.
Click on Upload and wait for the message telling you to wait to disappear. Then click Preview Message to make sure you did what you wanted to do. Then click Submit.
If you are the first to post in the thread, you will see the paper clip at the top of the message box. Proceed as described.
