Welcome to the forums, man.
If you are talking about how people post pics in their posts like this:
Then here is what you need to do.
1. go to
www.photobucket.com and create an account. Upload the pictures that you want to post.
2. When you click on the pictures that you uploaded, you should be brought to an enlarged view. Then on the left hand side of the page should be a box that has different links in it to share with other people.
3. You need to copy and paste over the IMG code to make it work. Here is an example.
[IMG]http://i412.photo

I put a bold
A in the link to break it so you know what it looks like.
Hope this helps.
