To post pics, select the "Go Advanced" button under the "Quick Reply" window at the bottom of the thread.
Then type in whatever you want but before you hit the submit button scroll down below your edit window and look for "manage Attachments". Click that and you will see a pop up window. On the pop up window click the browse button and browse on your computer to the pic you want to post.
Do again for each pic you want to post.
Then click the upload pics button. This will copy the pics from your computer to our server. Then you can close the pop up window and click the submit post button.
Sounds harder than it really is. You'll get the hand of it I'm sure.
