[Zope] How to link inline graphics on a Zwiki page?

Zwiki newbie Trying to build a Zwiki for Python and multimedia. Would be very helpful to have inline thumbnail images amiong the Zwiki text linking to larger images when clicked. Can't find the syntax to do this. Does anyone know of any Graphics-oriented Zwikis I can look at as examples or How-Tos out there? thanks ./Jason
