Not able to customize the Thank You page to include my custom image

Hi, I've been trying to upload a simple image in the thank you page, but can't erase the white space pre-defined in this page, Is there any way to fix it? Please se the image to figure it put what's happening.

Thanks

Will

I did a test submission to your form (http://www.jotform.co/form/73199271462866) and I was not able to replicate the issue. Here's the Thank You page for my test submission:

Is your form embedded on a website? If yes, please provide the link where the form is embedded so we can check it.

Thank you.

Hi...
  You can try it again and see the problem, it was pointing to a
website before, but I need to have the "thank you" page in jotform, not
outside of it.
Many thanks in advanced.
