Adding an image to the heading

Hi,

I want to add an image to the heading CE.
There should be a different image for each heading-type.

So in my opinion i need to change the class "element-header" to a unique one per type (like heading-type 1 = element-header-1,heading-type 2 = element-header-2 and so on)
After that i could add the individual image as an background-image with CSS.

Is there a way to change the element-header?
Or is there a better solution than mine?

Start by locating the markup that renders the element-header class and how heading types are distinguished in the theme. Review the existing CSS around the heading styles and determine how each type can receive its own image. Done means each heading type displays its intended image without affecting other headings.
