If you just want to post pictures of your car then the exterior interior forum is ok as well as the pits.

As for hosting them, you have 2 choices. Use 2gnt or use another like webshots or photobucket.

If you choose 2gnt then you must load the pictures in the pits. Go to post new message and look towards the bottom of the post page. CLick to load attachments. When the attachments page comes up it will look pretty generic and should be self explanatory. When the picture gets loaded, the page will update and you will be given an address of the picture. Copy and past the picture to whatever thread you want. As far as the page you opened to make a new post, just use your back arrow to get out of it.
