user warning Errors!

using Drupal 6.4:

I'm getting this error when updated a node (book):

user warning: Duplicate entry '152-0' for key 1 query: INSERT INTO drupal_image_upload (fid, nid, vid, tid, description, weight, thumbpath) VALUES (0, 43, 152, 0, '', 0, '') in /XXX/modules/image_upload/image_upload.module on line 373.

it says the page has been updated but no picture are showing up, even i create a new page and the content types are enabled + upload images/view uploaded images permission are set..

the image upload previews are showing when editing or posting but final images are not showing up in the nodes...

any help please??
