PhoTop - Sort images by size, find large images & Check image size and resolution

PhoTop is a photo utility app. It could help you in below ways:
1, Quickly check image size.
Browse all images and see the size of each image just below the thumbnail. Different colors indicate different sizes, for example: images larger than 5M are marked in red.
2, Sort images by size, and quickly find out large images.
You can also choose to show only high resolution images(for example: >4000x3000).
3, Play animated GIF.
4, Check Live Photo's Size
A Live Photo is composed of 2 parts: an image, and a video. PhoTop shows you both the image size and the video size, so that you will have a better idea how your storage is used.
