I moved this over to the web graphics forum so you may get more answers.
You can use the following code:
<img scr="http://www.yoursite.com/files/graphicname.jpg">
The url is the location of your graphic.
www.yoursite.com changes to your site url
files or
images is probably the path
graphicname.jpg changes to your graphic name and type
There are other things you can add to the code like the graphic size, alternate text, etc. Example:
