I'll check this out. THKS

Remember with IH you only need to upload only 1 image (main image) which will the largest image you want display.
Ok on the first item picture I uploaded from image handler....
Pop-up large still has no water mark, it's set to one in the admin.
I see it's not in the cache. I did un-install and redid everything - checking each file.
Second attempt ..... still not working on large image or on the product listing page. seems like the only place my water mark shows in on the product_info page on the main product image listed there!
I know it can not be this hard.... geez I just can not see it... What in world did I do wrong?
BTW My image and bmz_cache folders are 777
