[Zope] Accessing .gif on disk with Python Product?

I am writing a python product and want to display a GIF file in some of the manage_pages. It is not meant to be the "icon" property of the class, just an image to be included in DTML. I included it in my class as follows: chooser = ImageFile('images/chooser.gif',globals()), but when I call it in DTML (<dtml-var chooser>) I get the following: <ImageFile instance at 014F1D90> I thought maybe I could use an instance of the Image class: chooser = OFS.Image('images/chooser.gif',globals()), but this doesn't seem to work. How do you create an instance of an Image in a Python Product? kh
