Are we free to add tag links to images to OSM as in this.

The https://www.bushtrax.com site is copyrighted so I assume that such links to the photos need to be either accompanied by permission or disclaimer or suitable licence or display of the copyright, etc from the copyright holder.
Does anything need to be documented on this page https://wiki.openstreetmap.org/wiki/Contributors#Australia.
Or is any url from the web of an image ok to be pasted without any further consideration other than relevance?
