Make an images folder inside src(/src/images) And keep your image in it. Then import this image in your component(use your relative path). Like below-
import imageSrc from './images/image-name.jpg';
And then in your component.
<img title="my-img" src={imageSrc} alt="my-img" />
Another way is to keep images in public folder and import them using relative path. For this make an image folder in public folder and keep your image in it. And then in your component use it like below.
<img title="my-img" src='/images/my-image.jpg' alt="my-img" />
Both method work but first one is recommended because its cleaner way and images are handled by webpack during build time.
