Q1. I cannot upload an image in the EditMode.
A1. First, check if  you have the permission to upload. See "Upload Image/File" . Other cases are shown below:

(a) Problem with Uploader CGI
Set execute permission on following files:
 system/fckeditor/editor/filemanager/connectors/perl/connector.cgi      
 system/fckeditor/editor/filemanager/connectors/perl/upload.cgi
Set write permission for scripts on
 system/fckeditor/editor/filemanager/connectors/perl/

(b) Problem with uploading directory
Set write permission for script on ($datapath)/(pageID)/Image/
