Here you go...
1.) go to where the picture is, somewhere on the net. (webshots, etc.)
2.) right click on the picture to bring up properties.
3.) triple click on the url til it's highlighted.
4.) right click til it says "copy".
5.) go to your post, paste, and add in front [*img] and the rear [*/img].Omit the asterik when you post. It's only there to show you the way it should look but won't work with the asterik. That's it!
