I posted a big step by step to this for you yesterday and then my browser crashed at the VERY END and I lost it :'(
HTML might not be working in your posts due to being in "Rich text mode". I ran into this problem while trying to teach my mother (furzicle) these same arcane secrets. In "rich text mode" what you see is what you get and you change everything through use of buttons.
If you are in html mode, however, insert pictures by typing [img src=""], with triangle brackets instead of square and within those two quotation marks the location of the image (will look like http://somedomain/maybesomethingelse/imagename.jpg or something). You usually get this by right clicking on the image and going to "copy image location" in the box that opens (in firefox anyway). Good luck!
