[Zope] Extending Standard Objects

[James W. Howe]

In my experimentations with Zope, I'm trying to extend the Image object to 
include caption information and formatting.  I've created a ZClass which 
has Image as one of the base classes.  I'm a little confused as to what to 
do next.  For example, what properties do I need to defined.  Do I just 
define the caption property?  Do I inherit any properties from Image 
itself?  I also noticed that because I subclassed from Image, certain views 
are created for me by default.  The "Edit" view is defined to use 
manage_main.  The "Upload" view uses manage_uploadForm.    If I want to 
enhance the functionality of the Edit and Upload view, do I just need to 
create new methods on my ZClass and point the view at the new method?  If I 
wanted my views to look just like the normal views (manage_main and 
manage_uploadForm) with only minor tweaking, where would I find the source 
to those methods?

Thanks
