ImageMagick is installed on the server I work. When I create a Photo product instance, if I see the properties of the image, several displays have been generated. I would like to display a thumbnail with :<dtml-var expr="image(display='thumbnail')"> but Zope generated the next error : Error Type: AttributeError Error Value: __call__ Traceback (innermost last): File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 114, in publish File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: test_photo_imagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 98, in publish File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: testimagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: testimagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/OFS/DTMLMethod.py, line 127, in __call__ (Object: testimagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: testimagemagick) File /zope/Zope-2.5.0-solaris-2.6-sparc/lib/python/DocumentTemplate/DT_Util.py, line 159, in eval (Object: image(display='thumbnail')) (Info: image) File <string>, line 2, in f Thanks in advance for the help you can give to me.
