content_type=file.headers['Content-Type']
if content_type.find('image')!=-1: #.find() is a method in Python2.0<


destination=context.restrictedTraverse('/cheng/rvdpas/uploadImage/'+folder)
    destination.manage_addImage(id, file, title)\


else:

destination=context.restrictedTraverse('/cheng/rvdpas/uploadDocument/'+folder)
