For some reason after installing Alfresco 3.4a Community on Ubuntu 10.10, the document preview would not work. After searching, I found a fix for that allowed the preview of PDF documents and image type files like JPGs, etc.,. http://plone.4aero.com/Members/lmarzke/alfresco-3.4a-on-ubuntu_lucidHowever, DOC, DOCX, XLS, XLSX files were not being thumbnailed and would not show up in the previewer. The solution was to make a change to the alfresco-global.properties for the "img.root" pathfrom: img.root=/opt/alfresco34a/commonto : img.root=/usrAfter this change the previewer and thumbnails are working.
