If your HTML code shows up as text, you input the code using the "simple" form or you were using the Standard editor window on the full-optioned format. In order to use HTML code, you need to be using the "customize" full-options listing format because the "keep it simple" format" does not support use of HTML.   If you're using the "simple" format, upper right corner, click the "switch" link and switch from the "simple" to the full-optioned listing form. Once you get to the "customize" full-options format listing form, scroll down to the editor window.   There are 2 tabs, one for Standard text input and one for HTML input.   Click the HTML tab and input your pic's HTML code there.
