How to properly move an image under the Hexo theme title?

Question

Node.js

There is a Claudia theme for the Hexo static blog generator . I want to redo it a little, but when I move the image under the header, the image scaling effect stops working. Tell me how to transfer so that the scaling effect is preserved?
