Thank you very much for your suggestion. My client uploaded almost 100 new products and most of them have problems. Delete them all and re-upload them will take quite some work..
I tried to delete some of the images my client uploaded and, without deleting the product, I uploaded new images. The images show up on the product list page but the product info page is still broken..
see here:

If you would click on the first product, you can see the product info page does not display correctly..
What should I do? Delete the product and re-setup the product again? Is there no other easier way to solve the problem?
