I get the " Image elements do not have explicit width and height -Set an explicit width and height on image elements to reduce layout shifts and improve CLS" suggestion in google pagespeed insights. This is for all of my products so it is a systematic error.
I am using Debut theme - Is there something I can do?

Hope this message finds you well and safe.
To fix the CLS, you have to take up space for a specific element. In your case, you should have a space reserved for images with a fixed height.The height will need to be given using css. And there should appear pictures.
CLS is an unstable indicator and the impact on the overall score is low. But it has a big impact on the UX. If there is a clear shift on the site, it can spoil the impression of your store. And this is not a system error, the product page uses the same template, so there are notes on CLS on every page.
