I have an object that looks something like:

```
var myObj = {
some : {},
stuff : 123,
in : {
    here : {
       variables : 'stuffety stuff',
       variables : 'stuffety stuff',
       variables : 'stuffety stuff',
       variables : 'stuffety stuff',
       image1 : 'img1.jpg',
       image2 : 'img2.jpg',
       image3 : 'img3.jpg',
       imageN : 'imgN.jpg',
       ...
       variables : 'stuffety stuff',
       variables : 'stuffety stuff',
    }
  }
}

```

Where N can be any given Number. I'm trying to get all the keys with "image" in it and push it into an array. So that the Result should look like:

images['img1.jpg','img2.jpg','img3.jpg','imgN.jpg'...]

How do i find those numbered keys, when not knowing how many of them there are. They can also be unordered. (image2 missing for example)
