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
