I'm working on creating an extension to Image which will allow a person to include caption and attribution information for an image. I'm calling this a CaptionedImage for lack of a better name. I've created the ZClass and added property sheets and defined some methods for my views. What I don't know how to do, however, is modify the way the object renders itself by default. For example, if I use the following: <dtml-var CaptionedImageObjectInstance> I get an img tag for the image associated with my object. What I want to be able to do is generate my own tags so as to include caption and attribution information in a standard format. How can I do this? Relatedly, does Zope support the notion of "super" in determine which code to evaluate. For example, in my CaptionedImage object, I would like to override the default behavior of view_image_or_file, but only if caption information was specified. If no caption information was specified, I would like to let the superclass version of the method be executed. Is there a way to do this? Thanks. James W.
