Configurable Image size for Title field

It would be great to be able to make the image size smaller for the title field. I’d make more use of the “image with text overlay” aspect of the Title field if I could make the image size/aspect ratio different than square (i.e. use the horizontal styling of the image field in other areas to make the Title field take up less space, when needed).


I’m also interested in how the image can be displayed better. The title (image) height seems to be set, and takes up a lot of screen. There seems to be no way of customising the dimensions.
Has anyone worked out a work-around involving inserting an image with particular dimensions, say?
