Please open your form using the form designer and set the background image like in the following picture.
It should fix the background issue
If you want to avoid the black line that is placed when the background image is repeated, I suggest that you use a background pattern instead (you can find some here: http://www.patterncooler.com/)
Please let us know if you have further questions.
