CKEditor, Image Upload (filebrowserUploadUrl)

I'm using CKEditor and would like to be able to allow users to upload and embed images in the Text Editor...

The following JS is what loads the CKEditor:

CKEDITOR.replace('meeting_notes', {
    startupFocus: true,
    toolbar: [
        ['ajaxsave'],
        ['Bold', 'Italic', 'Underline', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink'],
        ['Cut', 'Copy', 'Paste', 'PasteText'],
        ['Undo', 'Redo', '-', 'RemoveFormat'],
        ['TextColor', 'BGColor'],
        ['Maximize', 'Image']
    ],
    filebrowserUploadUrl: '/notes/add/ajax/upload-inline-image/index.cfm'
});

Where I'm stuck is with filebrowserUploadUrl. What is that URL supposed to return to CKEditor to get this process to work?

Thanks
