PrintRecord layout and printing attachment images

Hi all,

Some of my records have images attached and when I print the record, I want to add the image. Ninox has a clickbox for that feature that I can use. So far so good.

The problem I'm facing is that the image always has the same (small) size and I cannot find any way to adjust that. The images printed are too small to see anything on. How can I adjust the size of the box for the attached image? In the print layout the print-attachment-images-box doesn't show so there must be an other way. Is there a formula for this of do I need to adjust something in Ninox? Btw I use the app so I cannot use (all) features that are for the online version.

Thanks in advance
