How do I improve my website according to the Lighthouse Chrome extension

Hi,
I have a 14-year-old handmade jewelry website. I would appreciate your advice for improving my website according to the Lighthouse Chrome extension.

Thank you,

Jenn

It is a pleasant simple design. The images of products are kind of small. I think you should add the option where you can zoom in to look at the big high resolution image to see all the details of it.
