Images dont have explicit width or hight

Hey, how can i set width and hight explicit for my pages in the EditorX Shop?

As I remember this is only Google’s recommendation so there will not be a situation of layout shifting when the image is loaded later than the rest of the content. According to what I saw, this problem does not exist in Editor X.
On live site they already calculating the physical size of the image and even if the image does not load its place is saved.

okay. but he is doing a lot of layout shifting so my performance could be better
