Thats not an Image object, its just a file object
or rather its repr()

I really doubt the open() part here.

No, it just uses repr() here, which maps to the objects __str__
Method which happens to render a HTML tag for the image.

if foo is an instance of zopes Image, foo has attributes
like width, hight and so on - in short, its your image.

It depends on what you want to do with it.

Everything you need to know about these objects is in the
Zopebooks API reference.
