What is the significance of using md5_file to compare images when troubleshooting image quality discrepancies?

When troubleshooting image quality discrepancies, using md5_file to compare images can help identify if the images are identical or not. This can be useful in determining if the issue lies in the image itself or in the way it is being processed or displayed. By comparing the MD5 hashes of the images, you can quickly determine if they are the same or different. 

$image1 = 'image1.jpg';
$image2 = 'image2.jpg';

if(md5_file($image1) == md5_file($image2)) {
    echo "Images are identical.";
} else {
    echo "Images are different.";
}
