How to change background?

I meet a problem of not being able to show the background picture that i put into the file “background” in the file public img. I changed the name of the background image i put in, but i’m sure that the name i put after the set screen is correct, which is the name “blurry”
When i open the game with “npm start”, the image for the last backgroud dissapeared and just turn into pure grey, the image i set did not load and i am really confisued TT

It’s not a good idea to have spaces in image paths, I would use dashes or underscores. If you do use spaces then you need to wrap this in double quotes probably. But better to avoid spaces

Thanks a lot!that is the problem
