this is my demo

package main

import (
	"fmt"
	"github.com/rwcarlsen/goexif/exif"
	"os"
)

func ReadOrientation(filename string) int {
	file, err := os.Open(filename)
	if err != nil {
		fmt.Println("failed to open file, err: ", err)
		return 0
	}
	defer file.Close()

	x, err := exif.Decode(file)
	if err != nil {
		fmt.Println("failed to decode file, err: ", err)
		return 0
	}

	orientation, err := x.Get(exif.Orientation)
	if err != nil {
		fmt.Println("failed to get orientation, err: ", err)
		return 0
	}
	orientVal, err := orientation.Int(0)
	if err != nil {
		fmt.Println("failed to convert type of orientation, err: ", err)
		return 0
	}

	fmt.Println("the value of photo orientation is :", orientVal)
	return orientVal
}

func main() {
	ReadOrientation("5242974a.png")
}

they report :failed to decode file, err: exif: failed to find exif intro marker
