Samsung galaxy 3S, battery is good, phone won't charge or power up
If your device is not modified, the best option from here may simply be to contact Samsung and ask about using your warranty to get your device fixed. All Samsung mobile phones have a two year warranty from the moment you receive the device, so if your device is still within that period of time you should be able to, for free, have Samsung fix the device and your pictures retrieved.

Use the Samsung website for more information regarding this.
