[Zope] cmfoodocument

Hi, I have CMFoodocument working on plone 1.04 with Zope 2.6.1. with cmfoodocument 0.1.4, libxslt-1.0.33, libxml2-2.6.0, libxml2-python-2.6.0. The problem is that I cannot see the images of the uploaded openoffice documents, when I try to open the images, I see error : Forbidden You don't have permission to access /doc/Pictures/2000000A0000283200001FBA39B9E377.svm on this server. Is there a way how I can fix this ? Greetings, Johan
