Hi Jan,
Thanks for reaching out to us!
Currently you can achieve this by dragging the border between cells until all of the photo is showing. It unfortunately isn’t possible to zoom out to include the entire photo in any other way – the system does this on purpose to fill the cells. However, in the future we may change this to allow the Size slider (in the right bar) to let you do this.
Let us know if you have any further questions.
– Ben
