Can Android Device Manager only locate your phone if it is signed in to your Google Account? My phone was stolen two days ago, and I have only just had internet access to start looking up ways to find it - or, more specifically, at least recover the photographs on it.
While I had tried to back up the images by loading them onto my laptop, for some reason the phone wasn't showing up under "My Computer" so I gave up...ironically this was the day before it disappeared (it was a new phone).
I am pretty sure it was signed into my Google account, but I hadn't changed any other default settings. I tried searching for the phone on Android Device Mananger, but it can't locate it - presumably because the thief/ves wiped it? I guess I'm just hoping that maybe the device manager can't locate the phone because it's off...
Otherwise, is there any other way at all that I can retrieve my photographs?

Thank you (:
To use Android Device Manager (ADM):


  Your device's location access need to be turned on and be signed in to your Google Account. Android Device Manager won't work for devices that are turned off or that don't have a mobile data or Wi-Fi connection.


No, you will not be able to retrieve photos remotely from your phone. You can check whether your photos were uploaded by default to Google Storage. To prevent from losing photos in the future, you can setup your phone to automatically upload photos to the cloud.
