You can update your company's logo in your form by
1) click the header field and you will notice the top toolbar change. You will notice the HEADER IMAGE
2) Once you click the button the IMAGE WIZARD will appear and you may upload a new logo or if you have the URL, you may use that as well.
Hope this helps.
