In the make a post or creating a new thread there is a manage attachments right below in the additional options. Your account has a limit on the the amount of total space your allowed to use. An easy way around this is to create an account on photobucket.com or any simular site and link the picture you uploaded there to this site. This is a great feature because you can post large pictures that you couldnt upload because of the limited space that you are allowed. Simply click the little icon above the posting area that has a mountain picture on it and put in the url there. Any questions or problems please post them here. I will be happy to help you.
