I can't upload images to localhost:3000(node js)

I wrote the code through node js. (localhost:3000)
I don’t know what route I should write to make the image appear. (whether it is
<img src="/forpicture/public/images/school.jpg"> or something else. )

there is no school image that I wanted to upload. what do I have to do :frowning:
I want to upload images that is in my computer, not the internet.
