How do you post pictures

I always see photos on the BST and wonder how they do that. I can add photos but I add them as files and can only add four files. I was wondering how to add photos so they look like this and I can add more than 4 photos.

Upload through a third party source.

Ex: tinypic, imageshack, etc etc. upload and copy the link. When posting add the image link and paste the link in between the IMG brackets.
