Header image "dynamic height" possible?

Hi there,

once a question again for that great Theme an Add-ons:

If i upload a header-image (-> Background Images -> Header), the space for the image is always set by "Element Spacing" Header - top and bottom.

Is there a possibility to make the space "dynamic", as the height of the current upload Header Image?
If the Header-Image is set to "contain" it would be great to see always the whole image.

Thanks in advance!

Regards,

Oliver
