What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.

Once you have a revised background image the updated version can be uploaded to your own website.
Next, use our inject CSS feature to include the updated background URL. Please see this link for more info:
Specifically, you'll want to update the URL for the background value.
Let us know if you have further questions.
