Woocommerce resize existing product images

Question

We discover that our Single Product images as set in Woocommerce> Setting > Products > Display are set to big. Single Product Image: 500 ×750px xHard Crop

I have tested plugin regenerate thumbnails but that does not work on the product images. Also test plugins Resize-image-after-upload. But that plugin does it for all images if bigger then a certain size. So not to use either. Try to get a plugin or functions.php code to re-size all existing product images to the right dimension. Without luck.

Question: Do you know a plugin or php code for functions.php that does resize all full product images?

Would be very helpful.

I use this one for rebuild thumbnails: https://wordpress.org/plugins/ajax-thumbnail-rebuild/

Answer 2

Theme authors can now declare image sizes via the add_theme_support function. Declaring image sizes this way will take priority over any other settings and also hide the image settings section in the admin area.

add_theme_support( 'woocommerce', array(
    'thumbnail_image_width' => 150,
    'single_image_width' => 322,
) );
