What are the potential reasons why images are not being saved despite the PHP code being implemented correctly?

The potential reasons why images are not being saved despite the PHP code being implemented correctly could include incorrect file permissions, incorrect file paths, or issues with the image file itself. To solve this issue, check the file permissions to ensure that the web server has write access to the directory where the images should be saved, verify that the file paths are correct, and ensure that the image file is in a valid format. 

// Check file permissions
// Make sure the directory where the images should be saved has the correct permissions
// For example, set the directory permissions to 755
// sudo chmod -R 755 /path/to/directory

// Verify file paths
// Check that the file paths in the PHP code are correct
// Use absolute paths if necessary
// For example, $target_dir = "/path/to/directory/";

// Validate image file
// Ensure that the image file being uploaded is in a valid format
// Check the file extension and MIME type before saving it
// For example, use functions like getimagesize() to validate the image file
