Why Does my background picture not show in my form?

I have set a background picture in my form:

https://form.jotform.com/210412489335049

I can see it shows well in the editor, but when I am looking at the live form I only see a blue background. Treid to refresh and look in different browsers. I also tried another picture without any luck.

Hi,

I have checked the form and I can see the background picture.

Can you check the live form again?

Looking forward to your reply.
