You first have to have a host such as photobucket. com. Make an account there, upload your photos and copy/paste the "[img]" link to post a photo onto a site. If you use the older version of photobucket, it'll give you a drop down as you scroll over a pic. IMG will be the bottom link. The new version doesn't. PB will ask you if you want to use the original version or new version. New version sux.
