BIll's explaination & Gunnar's weblink are perfect answers. I might only like to add that utilizing your PC's copy/paste function will make posting multiple pics faster as well. Say I want to post 7 pics: I simply copy and paste seven "[ url ][ /url ]" command's into the posting, and then can quickly copy/paste the web adresss of each pic link afterwards. It's much faster than painstakingly typing each pic's address with URL commands in individually.
