Error when adding an image to the template

[AndPDale]

Hi,
I am looking to add a static image to the resulting template. The image will be the same on every resulting photo array.

I have created the template in draw.io and imported it into Pibooth. I have regenerated the images (pibooth-regen) but I am seeing the following error message:
"pibooth_picture_template.TemplateParserError: Too many captures positions (5) in template 'Page-1' (1 to 4 expected)"

I have included the xml I am using as a TXT file
photograph.txt

Hi, you can't include images in the template, templates are only for captures place holder.

For static image, use background or overlays keys in the config
