checklist:

1 confirm the editor: XOOPS/class/xoopseditor/FCKeditor/

2 confirm scripts handling upload for FCKeditor in corresponding module folder:
- XOOPS/modules/$module_dirname/fckeditor.connector.php
- XOOPS/modules/$module_dirname/fckeditor.upload.php
- XOOPS/modules/$module_dirname/fckeditor.config.js

3 make upload folders:
- XOOPS/uploads/$module_dirname/
- XOOPS/uploads/$module_dirname/Image
- XOOPS/uploads/$module_dirname/Flash
- XOOPS/uploads/$module_dirname/File

4 if you prefer to store images from all modules into a unified folder, skip step 3 and create:
- XOOPS/uploads/fckeditor/
- XOOPS/uploads/fckeditor/Image
- XOOPS/uploads/fckeditor/Flash
- XOOPS/uploads/fckeditor/File

5 set write permission for above folders
