There was a picture of a deserted amusement park at night. The Ferris wheel was still, but in the photo, there seemed to be a figure sitting in one of the carts that was not supposed to be there.

The element of mystery. Just one picture leaves a lot to the imagination. For example, a single photo of a dark cellar with a small, unidentifiable object in the corner can make your mind race with all kinds of spooky ideas.
First, analyze the elements in the creepy picture. Think about the emotions it evokes and the possible characters or settings it suggests. Then, build a plot around those ideas, adding twists and turns to make the story engaging.
One could be a picture where a figure is just barely visible in a dark corner when you look over your shoulder. It's the kind of thing that makes you wonder if there was something really there or just your imagination.
A picture of a long, empty corridor in an abandoned hospital. There are bloodstains on the floor and a wheelchair at the end, as if something terrible happened there. The dim lighting in the picture adds to the horror.
I'm not specifically familiar with '94 one picture horror stories'. But generally, in one - picture horror stories, a single image can convey a lot of horror. It might be a spooky figure in the corner of an old, dilapidated room, or a strange symbol that gives off an evil vibe.
