You are posting this as an html query. The simple answer is to put the code (given in the previous post) at the point where you want the picture to appear.
However, reading between the lines, I suspect that what you actually want to know is HOW to put a picture on your site with the site building software you are using. As Bravenet does not place any restrictions on which of the hundreds of possible site building programs you can use we need a lot more detail in order to help.
