When you view the galleries, you will see thumbnail images. You don't want to download those. You want to download the big images the thumbnails link-to. Open in Chrome or Safari. Then use the download icon to immediately download the "big" high-res version. Tap/click the image to see it larger.
The photos are more than a little out of order. Sorry about that. It’s best to look through all of them to find all of yours. 🙂
