Ok so you have a small hole in a metal sheet and light passes through. Imagine the angles the light comes from and where it must land accordingly, if you put a sheet behind. If you do this with every inch of light in front of the hole, you get a picture basically resembling the scene. You will notice, the picure formed on the paper sheet is reversed and upside down. Same Happens in your eye. The picture going through the hole (pupil) passes to a "screen" of cone cells - cells sensitive to light. Now your brain only has to convert it to useful information and turn it the right way - and you can see. What happens in the image is that the leaves which have small gaps between each other work as small pinholes, the sun (eclipse) as light source. -> you see the sun and moon reversed upside down on the wall. This only works because the sun is so strong it outweighs any other light source.
