I believe in the about forum section you can find help on posting pics. From the reply to thread screen click on the paperclip icon and then hit browse when the next window comes up. From there you have to select a picture file of your rocker and double click on it. That should automatically upload the picture. Then you need to hit the attach button to for it to download to the post.
Make sure your pictures are in the default picture file of your computer. Makes them easier to find when the window comes up to download them.
Hope that's not to confusing.
I'd tell you how to use photobucket but that might give you fits.
