[Zope] Newbie Question

[Michael]

I am trying to add build a small site using Zope that will have the option of 
viewing a text only version as well.  I have created a standard_html_header 
which also contains objects for the site logo and navigation information. 
These are the only graphics on the site. My question is, do I need to create 
a separate header for the text version, or is there a way that Zope can 
determine what page is calling the header and then insert the proper object? 

ie: index_text_html is calling standard_html_header so "text_logo" and 
"text_navbar" gets called. Or, index_html is calling the standard_html_header 
so "graphic_logo" and "graphic_navbar" gets called.  

I'm not real good at explaing things, I hope you can understand all of this;-)

Thanks,

Michael
