Thank you for this snippet ! I was really bothered by Prestashop not having a native bulk thumbs regeneration for big ecommerce... You saved my day :)

@evgenij-sobolev, you have an error because you need to change the 2 first lines.
The first one needs to point to the root folder (from the location of your file).
Same thing for the admin folder, you have to rename it as it is in your prestashop install (admin123xyz...) ;)

I'm actually amazed this snippet still works after all these years. :)

Hi, thanks for the script any idea to limit the rgeneration process only to some product_id?

Made my day.

If you are gonna use this, and you gonna place it somewhere under your public_html/http_docs/whatever public folder accessible over http, you should add that bit on top of the script, as otherwise you may be introducing a security issue on your server:

if (php_sapi_name() !== 'cli') {
    die();
}

THANK YOU SO MUCH

regenerate-images.php works on Prestashop 1.7.8.9
