To maintain high quality print yet keep the file size down (which helps reduce the upload time) our software only uses the jpeg format. All digital cameras create this format by default and this is the most common format for scanners and image editing application.
If you wish to place images in other common formats such as TIFF, PNG or BMP you can still add these to your photobook layout using the image editor. Simply double click on any empty image frame to launch the editor and select 'Open' from the file menu.
(Please note that our software does not currently support transparency)
