Hi, I have just implemented imagefield import - which actually works really well, even though I seem to get all these warnings on the Node, where I have to save the imported images. 

   * warning: Parameter 1 to filefield_validate_is_image() expected to be a reference, value given in /var/www/www.midt-domaine.dk/www/sites/default/modules/filefield-6.x-3.7/filefield/field_file.inc on line 160.
