Blurry Thumbnails

Hi there,

Your URL is going to a 404. Can you double check?

Thanks! :)

Hi Tom,

sorry for delay but I wanted to check if the issue was eventually related to image quality and compression. So I decided to start from scratch once again. So, fresh new install and now all the product images that have been upload are higher quality and less compressed...

take a look at this address...

https://3store.it/categoria-prodotto/smartphone/apple/

All images are quite sharp and well defined, but if you go in a single product page, for example:

https://3store.it/negozio/apple-iphone-8/

you'll see that the thumbnails are quite blurry... while the main image is sharp and well defined...

Hi there, you may want to try regenerating your thumbnails with this plugin:

Hi David, tried that already but with no results at all...

OK, Woo's latest update set the gallery thumbnail to a fixed 100px x 100px size. Which is being scaled up by the layout. You can use this filter to change that to a higher resolution.

add_filter( 'woocommerce_get_image_size_gallery_thumbnail', function( $size ) {
    return array(
    'width' => 150,
    'height' => 150,
    'crop' => 0,
    );
} );

Try increasing it using this method and then regenerate thumbnails.

Thank you very much David, where should I place this piece of code without messing up the whole site (I'm not that confident in this kind of programming...).

Here is an article on adding PHP, which includes a link to the Code Snippets plugin which is the simplest way to add these codes:
