I am making a website and I have run into a problem. I need to make an image change when I click on it and that change it back to the original image when I click again. Can anyone help me with this? 

This is the code I have tried so far but it doesn't seem to work for me.

```
<img width="200" height="150" align="right" onclick="changeImg(this, 'Images/Rest2.jpg')" src="Images/Rest2.jpg">

```

```
function changeImg(img, Images/Rest1.jpg) {
    img.src = Images/Rest1.jpg;
}

```
