He mostrado con éxito información sobre los perfiles de los usuarios administradores Fotos usando la API de Microsoft Graph en PHP, a continuación se muestra el código que usé

<?php
session_start();
echo $acc = $_SESSION['access_token'];
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => "https://graph.microsoft.com/v1.0/me/photo/$value",
    CURLOPT_HEADER => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_HTTPHEADER => array(
        "authorization: Bearer $acc",
        "accept: application/json",
        "content-type: application/json; charset=utf-8"
    ) ,
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
$res = json_decode($response);
$res1 = json_decode($response, true);
$res1['@odata.context'];
echo 'photo <img src="data:image/jpeg;base64,' . base64_encode($res1['@odata.context']) . '"/>';
echo '<p>photo Name : ' . $res1['@odata.context'] . '</p> 
      <img src="' . $res1['@odata.context'] . '"><br />';
echo '<pre>' . print_r($response, true) . '</pre>';

if ($err)
{
    echo "cURL Error #:" . $err;
}
else
{
}
?>

JSON regresó:

MI problema es que cuando traté de mostrar la imagen en un enlace de imagen en php según el resultado de json Curl en php, sí muestra la imagen.

¿Cómo convierto los datos de imagen devueltos binarios a formato legible de imagen del navegador?

Below is the new error message after implementing Marc Solutions

CURLOPT_HTTPHEADER => array(
    "authorization: Bearer $acc",
    "accept: image/jpeg",
    "content-type: application/json; charset=utf-8"
