Ordering images in a gallery can be very difficult when you are limited to thumbnails. I must switch back and forth between my post and my camera roll to identify each image and make sure each is in the proper place. Click/tap to view an image is a common pattern that is missing here. I use it all the time elsewhere to reassure myself that I uploaded the right images and put them in the right order.
