Exibi com sucesso informações sobre perfis de usuários administrativos Fotos usando a API do Microsoft Graph em PHP, abaixo está o código que usei

<?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
{
}
?>

O cabeçalho retornou com uma chamada bem-sucedida:

}

Meu problema é que, quando tentei exibir a imagem em um link de imagem no php conforme o resultado do json Curl no php, ele mostra a imagem.

Como faço para converter os dados binários da imagem retornada no formato legível da imagem do 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"
