Kan man indsætte link til et billede i dette JavaScript?

Hejsa.

Kan det lade sig gøre at tilrette dette JavaScript, så der også vises et billede, dér hvor der vises et text-felt?

Scriptet er kopieret herfra:
http://www.dynamicdrive.com/dynamicindex5/jumptop.htm

Og indeholder disse 2 filer:

JaveScript-linket i html-dokumentet:

<script type="text/javascript" src="js/jumptop.js">

Selve JaveScriptet, hvori jeg ønsker at indsætte link til et billede:
