27 Controlling Image Display

  • Let’s get started by figuring out how to load images. You can render the <Image> component and pass its properties just like any other React component. But this particular component needs image blob data to be of any use. A BLOB (short for Binary Large Object) is a data type used to store large, unstructured binary data. BLOBs are commonly used to store multimedia files like images, audio, and video.
