One way to do it would be something like this:

class SomeImage(grok.View):
   grok.context(Interface)
   def render(self):
     # This will return an file object as the response content.
     # Zope knows how to deal with returning file contents.
     return open('path/to/image.png')

In you pagetemplate you can then do something like:

   ...
   <img src="" tal:attributes="python: view.url('someimage')" />
   ...

But you might be better of by registering a DirectoryResource for the 
directory holding your images.
