Render nativeImage


In my main process I make a screen capture, which is working great, and returns a nativeImage.
I want to render this image in a renderer window.

Should I save it to disk, and referencing it with a img tag?
Should I send it to the renderer by base64 encoding it and using data-URIs or is this too slow?
Are there other options for rendering a nativeImage?

Kindest regards!
