La sortie affichée est "Invalid File Extension" pendant que je télécharge un fichier jpeg.Obtention d'une erreur 'Extension de fichier invalide' lors du chargement d'un fichier image

<body>
<form method = "post" action = "upload.php">

<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
