Subject: [Zope] how to check attribute or property of a object ??



hello,
Every dtml-image object has width and height as a default property.
I want to check if a dtml image object has 
width (attribute or property) > 1
something like
<dtml-if expr="objectname.len('width')>1">
do something
<dtml-else> do something else
</dtml-if>
can anybody please tell me the exact syntax ??
can i use len ??
thanks for the help.
