Well the way I would do it is to go to www.photobucket.com and create an account if you dont already have one and put them in there. I think the limit for each post is 10 pics. To post pics after you download the pics to photobucket, underneath the pic there are 4 links, RIGHT click on the 4th one and it will copy automatically and paste it in your post, put each pic on its own line, i.e. hit enter after you paste each picture link.
That is an awesome build by the way, love the detail and the BIG dump truck.
