How to use local static images in Svelte

I was following the tutorial (https://svelte.dev/tutorial/dynamic-attributes) to import local image files. But it didn't work. The image was not found in the app.

Where do I need to locate these images in order to make it works as in tutorial?

let src = './images/background.jpg'...<img {src} alt="background image" />

The browser showed Image not found.
