Where can i find the url of the product images in the db?

[Fat Mike]

Hi to all, i'm a new user of prestashop and this is my firt post in this forum.

I'm working on an installation of prestashop that have a big catalog imported from another site, but there isn't product images.
So I need to import all images from the old site, without reimport the catalogue. I need to write a script to obtain this result but i can't find the field in the db that contains the url relative that link the images.
Where do I need to watch? :-)

I searched in the forum for an answer but my attempts didn't give results to me.

Thank you all.
