how do you post pics?
When you hit the "Reply" button, on the lower left hand corner of the reply box it says "Additional Options"
Click on that and you can use the Attach button to add a picture. there is a size limit though on the pictures you upload from your computer so you can also register at a site like
www.photobucket.com and upload pictures there for free. they will supply you then with a link to the pictures hosted on their website and that way you can poster larger pictures than the built in uploader allows.
