Simple, M'boy. Ask and you shall recieve.
First, make an account at an image hosting site like Photobucket or Imageshack.
After that, submit your pics into the site.
Then, after that, put the given URL of the pic in
tags.
example:
[img]http://img.photobucket.com/albums/v605/Swiftman/capn_crunch.jpg[/img]
Like that. Without the code thing, it'll end up like this:
Simple as pie, m'boy!
