How to compare JPEG pictures by C#

// Compose report about differences in JPEG images

// Pass main file path to Comparer constructor
using (Comparer comparer = new Comparer("source.jpeg"))
{
    // Provide paths to other JPEG pictures
	comparer.Add("file_to_compare_1.jpeg");
    comparer.Add("file_to_compare_2.jpeg");
    comparer.Add("file_to_compare_3.jpeg");
