Many thanks for your patience. When a company becomes insolvent of ceases to exist that does not mean that all its intellectual property rights, such as copyright, ends too. They will continue to exist even after the dissolution of the company so to assume that just because the company ceases to operate or exist, there is no protection against its intellectual property, is incorrect.
Also another consideration is that photograph copyright automatically belongs to the person who created the photo, which would be the photographer. They may have given a company licence to use the photos and to extend the copyright to them but in the end they would be the official copyright holder. So even if a company was to lose their copyright over photos, that could still be retained by the photographer.
Therefore, in the circumstances you would still very likely require the consent of the company, or those running it, or the photographer of the photos to be able to use them.
