Coroner Peter Ryan initially suppressed all images, but later overturned that decision to allow four selected photographs to be released to the media. However, Mr Walker challenged that decision, taking it to the High Court, saying it breached his copyright and the coroner had erred in his decision.
In his application to the court, his legal team said: "There is an assumption that the absence of a suppression order positively prohibiting publication is the presence of a right to publish what is otherwise protected property."
However, Justice Alan MacKenzie ruled the public has a right to view evidence presented at an inquest.
"Because every inquest must be open to the public, it follows that any evidence given at an inquest is also open to the public," he said in his decision, released today.
Owning copyright of an image "does not confer a privilege or immunity preventing a witness from giving evidence", Justice MacKenzie said.
"Copyright is therefore not a ground for refusing to produce a document under compulsion. That reinforces the conclusion that copyright is not a relevant consideration for the making public of evidence which is voluntarily produced."
However, he noted that "nothing in this decision is intended to express any view on whether, when copies of the photographs are made available to any media organisation, any use of them will be protected by the Copyright Act 1994."
A Transport Accident Investigation Commission (TAIC) report into the crash found errors made by pilot Lance Hopping, 53, ultimately resulted in the fatal crash on the day.
It also established he had cannabis in his system at the time of the accident.
The release of the photos has been postponed until 5pm on November 4 to allow for a potential appeal to be lodged.
