The Zoomify showImage function supports inclusion of optional parameters - such as zInitialX, zInitialY, and zInitialZoom - in the form of a delimited string as in prior examples, or as an object, as in this example. View the source of this example to see the format used. Note that this approach is useful where the showImage function is called in a context where the '&' character cannot be used to join multiple parameters together, or when using the zOnReady parameter to assign a function to execute upon initialization of the Viewer. See the Parameter List in the Documentation folder for more information.
