The Gallery and the Organizer are not compatible. The folder that stores the old
Gallery clipart will be visible in the Organizer but the catalog and keywords will
not, you will have to supply them manually. You can use the Clip Gallery if it still
on your computer, it is in a folder similar to this:
C:\Program Files\Common Files\Microsoft Shared\Artgalry
Drag the CAG icon to your desktop and create a shortcut. It functions as a standalone
application. You cannot insert from it but you can drag and drop. You can also access
it in Publisher, insert, object, scroll down to Microsoft Clip Gallery.
