Snapfish has a pretty simple interface that allows you to upload from your computer, iPhone, Android phone, Google Photos or Facebook. But not from Amazon Photos.

At some point (probably because I was running out of Google space) I set my phone up to upload photos to Amazon Photos. There are a ton in there. I want to use some pics to make some memory books for Christmas, so I need to get 200-300 images from Amazon Photos to Snapfish.

I assume I will have to re-download them from Amazon Photos first to my computer or Google Photos (can I even do the latter?). Recommendations?
