What do you mean by "this effect"&#x202f;? The name of the image is Lighting effect.png, you uploaded it here, apparently it was stolen derived from https://gameovermangameover.deviantart.com/art/Invasion-324947082

Somebody converted it to grayscale and emphasized the contour, a simple image viewer like XnView should be able to do this. But the original already had the lighting effect, no idea how to do that, and it's no general wiki design question, maybe you need some "graphic workshop" or photoshop expert for your question.
