How do I recover photos taken from guest account in andriod 5.0

On my Nexus 5, with Android 5.0.1, I had switched to guest user and had taken some photos. Then I switched back to my admin user. A day after I switched back to guest user to get those photos and started a new session instead of continuing the previous session and I lost all my photos. I know starting a new session would have deleted all data of previous guest user as it is temporary data, however is there any way I can recover those photos deleted from guest account.
