Invalid content-type, should be image/jpg, image/jpeg, image/gif or
image/png.

You are forgetting to start the session with session_start():

session_start();
$tid = $_SESSION['id'];

Alternatively, you could also pass the ID through the image URL and read it
from there:

echo "<img src='echo_image.php?id=$id' ...>";

Make sure that you check that the ID is actually a number.
