By sample logo images, do you mean these?
If these are the ones that you would like to remove, please note that it is easy to do so from our Form Builder.
From the Builder, all you need to do is select the Sample Image and click on the red X to remove it from the form, as shown with number 1 on the image below:
If you do not want to remove the image, but only to change it with your own, you can click on the wizard button as marked by number 2 above, and set your own image instead of the current one.
Please let us know if you need any help setting this up, and we will be glad to assist you.
