    I would suggest you to take a look on this link that will help you to know the size an image should have in order to be properly displayed in the form as background: http://www.webmalama.com/the-best-full-screen-background-image-sizes-for-web-design/ 

    I have checked the image you're currently using and I can see it is a bit huge, it currently has 5175 x 2275.

    If you would like the image to display in a better way as it currently displays then you could simply inject this CSS code to your form: 

    .supernova {

        background-size: cover;

        background-repeat: no-repeat;

        background-attachment: fixed;


    This guide will help you to inject it to your form: 


    Here's my cloned form of yours where you can see how the code works: https://form.jotform.com/63065619159967 

    Hope this helps.
