Hello @freelylw ,
It looks like my Storefront was a bit customized so I had those options. By default, Storefront doesn’t allow you to change the image size as it is coded directly on the theme files. If you are interested, you can check the FAQ section (at the last) of this article: WooCommerce: How To Change Product Image Size
So, you do not get those settings to change the image size. If you need to update the default image sizes created by Storefront, you will need to add custom code to your theme’s functions.php
file that overrides the default value. An example code would be:
add_filter( 'storefront_woocommerce_args', 'storefront_args_override', 10, 1 );
function storefront_args_override( $args ) {
$args['single_image_width'] = 600;
return $args;
}
You will need to Regenerate the thumbnails after you add new image sizes to the theme.
If you aren’t familiar with codes I recommend getting in touch with a developer for suggestions.
I hope this clarifies the confusion.
Thank you ??
