Finding

Placing the image subject correctly and putting breaks (soft returns using Shift/Return) in the header will mean it doesn't run across the image.

In general, the image subject will need to be within the middle third of the image, to the right-hand side of that middle third. This will give room for the header and mean the subject is not lost when the image is cropped for mobile devices such as phones or tablets.

This image shows the subject is placed in the right-hand side of the middle third
a hero image with the subject placed to avoid the header
This is a closer crop on the subject but the important detail (the subject's face) is still placed on the right-hand side of the middle third of the image
