BiRC Photo Wall
Insert photo, edit details, print & cut
Pre-loaded with a public-domain photo (Mae Jemison, NASA) just to demonstrate the crop tool — replace with your own.
Drag the photo itself to reposition it within the box. Zoom in first if you need to move it further than the default crop allows.
Photo is fixed at 6 × 8 cm.
When printing: set scale to "Actual size" / 100%, not "Fit to page" — otherwise the cm sizing won't be accurate.
