Right, here goes, you need to get some web space to upload your pictures to, a good one is
www.photobucket.com Sign up to create an account and upload pics from your pc to your photobucket account. Once you've done this there will be three text fields below your pic in photobucket, copy and paste the last one that has IMG tags in it and put it in your posts and it will show the pics.
Taken from the thread on how to post pics
Hope this helps,
