Product page image (bigpic) other than Cover image

[perusi]

Hi,


I`m using Prestashop 1.4.2.5 version with Prestashop Alt Theme.


How can i display in product page (product.tpl) an image other than the cover image. I managed to do this on an old version, but now i cannot find the solution.


Any ideas?


Thanks
