I need help to put small images next to the options that are available in choiceBox. Do I have to code it or can it be done in scene builder ?
Hmm... Maybe this link will help?

You can try to use ImageView. You're going to need your images in a file in your project, but you can link those through Scene builder. https://www.youtube.com/watch?v=ePT4maOtjVA This guy gives an awesome explanation and demonstration on how to do it.
I agree with the imageview object, it allows you to put images into your scene. You can if your savvy enough to change the image next to the choicebox to change images based on the choice from the box.
