Most 'photo editing' programs have the facility to resize images proportionately. However, we understand that not everybody has photo editing software, so we offer a free image resizing service for members. (Non-Members will be charged).
Simply send you images to firstname.lastname@example.org and they will be resized and uploaded for you.
If your images are very large and you are unable to send by email, go to www.wetransfer.com and send using this free service.
