Hi Martin,

As specified in a response to my own post, I've found a solution.
The problem is probably due to a inappropriate dependency declaration in 
the zope.container module.
In fact zope.container use ZODB3 for their tests but ZODB3 is declared 
in the install_requires list in place of extras_require into setup.py.

Everything works fine after modifying the setup.py file.

BUT I wonder if the way that z3c.form compute resource url stay 
compatible with zope2

from zope.site import hooks
class ImageButtonAction(image.ImageWidget, ButtonAction):
     zope.component.adapts(interfaces.IFormLayer, interfaces.IImageButton)

     def __init__(self, request, field):
         action.Action.__init__(self, request, field.title)
         submit.SubmitWidget.__init__(self, request)
         self.field = field

     @property
     def src(self):
         site = hooks.getSite()
         src = zope.traversing.api.traverse(
             site, '++resource++' + self.field.image, 
request=self.request)()
         return src
