To OP, as upper image itself does not name stuff:

" I know, it can be seen from the link, but the legislature wants it ..."Hmm. Is that EU legislation ? Any reference ?
I think you can't link to image itself even if adding copyright notice.
Reason, at least, you are then eating server resources without any effect to server admin/owner.
My gut filling would be, don't link directly to image, linking to page where it is, is OK regardless of image copyright.
