I'd like to use this! But I have questions. Tell me more about the automatic rotation, and in general about how images are fit to cards when the aspect ratio differs. I'm also curious about print resolution.
Well essentially the platform simply looks at the difference between the width and height, and rotates to fit a 4x6 aspect ratio, gravitated towards the center of the photo. It works best with photos taken directly from a smart phone, uncropped. It also scales the resolution if its not high enough, but this typically isn't an issue if the photo was taken with a modern smartphone today.
