Photographic evidence of time travel

Skeptics often say that they require - photographic evidence of time travel, and this is one thing that troubles me. How could I or anyone else produce such evidence... For example, a newspaper headline could easily be created in photoshop. OK when the plane crashes or other disaster takes place, I could be accuse of sabotage and put in prison.

Please write to me on how one would confirm evidence of time travel that could convince. The idea is that is would be something epic.
