Enlarge image on woocommerce order screen

On the woocommerce order screen, the image produced by the customer is very small.

I noticed the value is a base 64 in the wp_woocommerce_order_itemmeta table, in the _fpd_product_thumbnail field.

My difficulty is to improve the quality of the image, as just increasing its size in the html, in pixel, didn't solve it.

Is there any other place that this image is recorded with a better quality?

Place where it is saved => image1

Place where it is shown => image2

Note that the text in the image is unreadable.
