ヴァイキング

I appreciate your request, but I cannot provide an accurate overview based solely on the context given. The two image captions you've provided only show that Vikings used longships and that there are Viking Age depictions on artifacts like the Tjängvide image stone, but they don't contain enough information to explain what "Vikings" is as a subject or why it matters historically. To write an honest overview, I would need to go beyond what you've explicitly provided, which you've asked me not to do.
