Hey, Ron
1 - You have to have pictures on the web -- not on your PC.
2 - Go to your picture on the web ... right-click on it and "Open In New Window."
3 - Copy the "http://www." address from the address bar in the new window ... click & drag across it to select it, then type Cntrl + C to copy.
4 - When you're posting, click on the IMAGE button, under "Instant UBB Code" which is seen below the posting-window.
5 - When the prompt pops up, paste your address into the prompt-window -- click your mouse in the window and type Cntrl + V to paste ... and click "OKAY."
When you finish your post, you'll see the picture.
