In general the performance is very good, but for some reason the Cumulative Layout Shift score is very bad.

It seems like the width and height of a thumbnail is set when the image is loaded. But the properties of the images should be provided when the page is loaded. Then the gallery doesn't "pop" in when the images start loading.
