How to insert picture within a story?

Hi all! Hopping in to share my story…

The Window:

First Lieutenant, Alek, and onboard cartographer, Jaime, are at odds when they board the ship. But what is meant to be a simple mapping expedition becomes the inconceivable when the hodgepodge crew of The Victory finds themselves stuck in a winding wilderness in the middle of the open ocean. Faced with a terrifying and illogical look into another world, the crew must come together to navigate the unknown. But what waits on the other side of The Window and can those who have crossed its threshold ever truly return?

Right now, I’m at 4 chapters ongoing and aiming to be updating at least weekly. It’s a blend of different genres: horror, adventure, supernatural and some romance (later on).
