This is only supported in beta ([https://makecode.microbit.com/beta](https://makecode.microbit.com/beta)). Use `imageLiteralColumns` and `imageLiteralRows`.

For legacy reasons, the parameter should be a string; but it is really an Image runtime object.

```auto
    /**
     * TODO: describe your function here
     */
    //% block="foo"
    //% imageLiteral=1
    //% imageLiteralColumns=12
    //% imageLiteralRows=3
    export function foo(i: string): void {
        // this is not pretty but basically, i is an Image
        let im = <Image><any>i;
        im.showImage(0)
    }

```
