Lucky Day (Doctor Who)

The entire poster: because the image is poster art, a form of product packaging or service marketing, the entire image is needed to identify the product or service, properly convey the meaning and branding intended, and avoid tarnishing or misrepresenting the image.

The copy is of sufficient resolution for commentary and identification but lower resolution than the original poster. Copies made from it will be of inferior quality, unsuitable as counterfeit artwork, pirate versions or for uses that would compete with the commercial purpose of the original artwork.

Main infobox. The image is used for identification in the context of critical commentary of the work, product or service for which it serves as poster art. It makes a significant contribution to the user's understanding of the article, which could not practically be conveyed by words alone. The image is placed in the infobox at the top of the article discussing the work, to show the primary visual image associated with the work, and to help the user quickly identify the work, product or service and know they have found what they are looking for.
Additional:When the episode titles for this season of Doctor Who were revealed, a collection of promotional posters advertising each of the episodes were also released. These teased their respective episodes by including references to elements of the story's plot. This poster specifically, includes a bulletin for a fictional podcast that is featured in the episode as well as several fictitious news headlines. Including this non-free poster art in the article in question, assists in providing a visual to the complexities of the plot described in the associated section. This includes the aforementioned podcast and how it relates to the way that UNIT was framed. Attempting to list and explain all the mentioned intricacies and headlines in detail through prose would ultimately become a copyright violation in and of itself. Therefore, reader understanding is better furthered by inclusion of the poster instead..Use for this purpose does not compete with the purposes of the original artwork, namely the creator providing graphic design services, and in turn the marketing of the promoted item.

As TV poster art, the image is not replaceable by free content; any other image that shows the same artwork or poster would also be copyrighted, and any version that is not true to the original would be inadequate for identification or commentary.

Use of the poster art in the article complies with Wikipedia non-free content policy and fair use under United States copyright law as described above.
