Addy Do this using fetch API const img = document.getElementById('img'); fetch(phpcodetogetimage) .then(response => response.blob(); ) .then(myBlob => { let url = URL.createObjectURL(myBlob); img.src = url; }); https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API The PHP is as follows <?php $pdo = new pdo(....your db details); $result = $pdo -> query(....your sql query); $row = $result -> fetch (PDO::FETCH_ASSOC); echo $row["imageData"]; ?>

Are the images stored as BLOB in your database or did you just store their file path? Please answer this question so that I will know the next thing to suggest.
