Unfortunately, this example doesn’t save the photos, but you can modify it to use the on board microSD Card to store the captured photos. You also have the option to take photos by clicking the Get Still button. In your Arduino IDE, go to File > Examples > ESP32 > Camera and open the CameraWebServer example.

The following pins are internally connected to the microSD card reader: When GPIO 0 is connected to GND, the ESP32 is in flashing mode. Additionally, GPIO 0 also plays an important role, since it determines whether the ESP32 is in flashing mode or not. You need these pins to upload code to your board. There are three GND pins and two pins for power: either 3.3V or 5V.
