Topic on User talk:Gadjiltron

The advice we give in the page I linked to is "Fair Dealing is always safe". You didn't create the image, or transform it in any way, so it's still under copyright by the game developer. What you would do in this case is in the image description put something like "Image capture of the title screen of Spybot: The Nightfall Incident‎ taken by User:Gadjiltron. All rights and ownership belong to (rights holder). The use of this reduced-size and -resolution image in the context of analysis and criticism of the work is believed to qualify as Fair Dealing/Fair Use under copyright law."

Then under the License heading, add the {{Fair dealing}} template.

That should do it.
