Variables within an object

I was reading a script and noticed that the programmer who wrote it had declared all their variables within an object. Example:

var variables = {
    height : window.innerHeight,
    width : window.innerWidth,
    image : 'img/image.png'
}

Why would one set their variables out like this instead of the traditional method (as seen below)?

var height = window.innerHeight,
    width = window.innerWidth,
    image = 'img/image.png';

It depends on the usage.

Perhaps the programmer wants to pass the fields height, width and image into a function, so he placed these variables inside an object to pass it as one parameter.

so instead of doing this

function doSomething(height, width, image) {
    // do something
}

he can do this

function doSomething(imageObject) {
     // do something
}
