Hello,
If you want in any case display your image, you can use the text block in order to insert some html for your image, see my screenshot :
You will find it from 
Main HikaShop Configuration, then 
Checkout tab.
Or else, if you want display it, 
only when you haven't available shipping method, this will required a custom.
You can add your
 image html directly in your HikaShop translation file.
See 
	this tutorial
 to see how to proceed modification on this translation key, "
NO_SHIPPING_METHOD_FOUND"
Hope this will fit your needs.
Regards
