How can I move the "form window" to the side to accommodate a picture?

I am trying to customize my form by adding a picture, but I can't figure out how to move the frame to the side

If I understand you correctly, you're trying to customize your form by adding a image but you can't figure out how to move the frame to the side? It will be helpful if you provide a screenshot where you want to put the image.

I am assuming that you want to put the image on the top right of your form beside the Heading field. Here's how:

1. Open your form, select the Heading field and click the Properties icon.
2. Go to Heading Image tab, upload the image you prefer.
3. Customize it the way you want and click Save changes when you're done. See screen animation below:

Hope that helps. If I have misunderstood your concern or you have any further question, please feel free to contact us anytime.
