[Zope] How to call image metadata using LocalFS?

[Ausum]

When iterating over image files within a LocalFS folder,  I'd like to expose
their width and height sizes.
Although LocalFS file objects can't store user-defined metadata for the time
being, it's possible to see an image's width and height values at its
properties tab. 
I've read the how to on "Using DTML With Local File System Objects" but I
couldn't find the solution there. 
Is it possible to call the width and height values of an image item, from a
LocalFs iterate procedure?

Thanks in advance,
