Support » Plugin: WooCommerce » regenerate thumbnails in background

  • Resolved HollyKNY

    Hello,
    I have a customer with a very small WooCommerce site, WordPress and all plugins current, running Woo 3.4.4. Out of the blue, yesterday he noticed a background task running “Thumbnail regeneration is running in the background. Depending on the amount of images in your store this may take a while.”.

    He hadn’t made any changes to the site other than creating the storewide notice, and then he noticed the same regeneration background message appearing on his second (also small) wholesale-only site. He left the browser open and 5 hours later, it said it was still regenerating thumbnails. He only has about 100 or so product images.

    Can you explain why this suddenly happened and if it’s anything to be concerned about? Thanks!

    Hi there,

    It could that WooCommerce updated automatically? I know that thumbnail regenerating was recently added to the core WooCommerce plugin (as opposed to having a separate standalone plugin for that).

    That said, the regenerating shouldn’t be dependant on having the browser open – this will happen server-side. You customer should be able to safely close that browser window without any side-effects 🙂

    Hello RK,

    He does not have WooCommerce set to do automatic updates. And we are curious why it is regenerating thumbnails at all. A product created 2 years ago, left untouched, should not have to have anything recreated by the system behind the scenes, right?

    Hi, @hollykny!

    You can read more about the image regeneration function added in v3.3. here: https://github.com/woocommerce/woocommerce/wiki/Thumbnail-Image-Regeneration-in-3.3#how-to-disable-background-regeneration

    If you’d like to disable this function, then you can use the following line of code:

    add_filter( 'woocommerce_background_image_regeneration', '__return_false' );

    You can add this code to either a child theme’s functions.php file or via a plugin that allows custom code to be added, such as https://wordpress.org/plugins/code-snippets/

    Cheers!
