What potential issue is the user facing with the image storage function in PHP?

The potential issue the user is facing with the image storage function in PHP is that the uploaded images may not be properly sanitized, leading to security vulnerabilities such as directory traversal attacks. To solve this issue, the user should ensure that the uploaded file is only stored in a designated directory and that the file name is sanitized to prevent any malicious input. 

// Ensure that the uploaded file is only stored in a designated directory
$targetDirectory = "uploads/";
$targetFile = $targetDirectory . basename($_FILES["fileToUpload"]["name"]);

// Sanitize the file name to prevent any malicious input
$targetFile = $targetDirectory . uniqid() . "_" . basename($_FILES["fileToUpload"]["name"]);

// Move the uploaded file to the designated directory
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $targetFile);
