What are the consequences of setting chmod permissions before saving images in PHP?

Setting incorrect chmod permissions before saving images in PHP can lead to security vulnerabilities, as it may allow unauthorized access to the images. To solve this issue, it is important to set appropriate permissions to restrict access to the images only to authorized users. 

// Set appropriate chmod permissions before saving images
$filename = 'image.jpg';
$filepath = '/path/to/save/directory/' . $filename;

// Set the permissions to 0644 for the image file
if (file_put_contents($filepath, $image_data) !== false) {
    chmod($filepath, 0644);
    echo 'Image saved successfully with correct permissions.';
} else {
    echo 'Failed to save image.';
}
