I noticed that you could just put a piece of code as the name (on linux of course) and it would automatically execute. No tricks needed. Is there any simple sanitation that I could use? like replace < and > with _

I've tried to replicate this without luck. Renamed an image to <?php phpinfo(); ?>.png.

You could try to wrap the $image variable in htmlspecialchars($image).
