Upgrading from Prestashop 1.4.7.0 to 1.5.6.0 and images urls

[patrmich]

Hi,

I upgraded my shop from 1.4.7.0 to 1.5.6.0.

I also transferred thousands of product images from the previous ../img/p folder to the new ../img/p folder.

But, some images are not displayed on the new shop.

As an example :
- on the 1.4.7.0 shop, one image url (before re-writing) was :
.../img/p/7508-13354-home.jpg
- on the 1.5.6.0 shop, the related image url (before re-writing) is :
.../img/p/13354-home_default.jpg

So, the image on the 1.5.6.0 is not displayed.
Such problem occurs for several hundreds of images (out of the thousands of the other images that display properly)

What is the best solution to solve the matter (without changing or regenerating the thousands of images that display properly).

Thank you in advance for any help.

Patrick
