Okay, hang with me cause this is my first day. Go to photobucket and sign up for an account. It takes a few minutes but it will be worth it. When you get done upload the pictures you want to post and it will give you a code for websites (http://). Copy the code it gives you and come back to this website. In the message box for posting text type this exactly.

Do NOT put spaces in front of and the end with the arrows, I had to so it wouldn't try and pull up a picture. Preview your message until you see the picture you want and post it. It might take a few tries, good luck.
