next and previous image buttons on product page

[jaanrs]

I'd like to add next and previous buttons to the product image on product page, so that the user can look through all pictures with these buttons, exactly like when the image is opened to fancybox.

 

How can I get the next and previous images in javascript? Im thinking something of this sort

 

function nextImage(){
    document.getElementById('bigpic').src = next $image.id_image

 

 

Thanks!
