You should first connect the Android phone to your computer in order to transfer photos. You can choose the best approach based on the available options, like :
- Use the Software Application built only for your model of your phone which has the possibility to not only transfer photos but to also perform firmware upgrade, contacts backup, etc. (the support software is available on the CD which arrived with your phone)
- Connect the phone to the computer using its own USB cable and enable USB Disc Storage. If your phone has an SD card, then your pictures are located in the DCIM folder.
- Use a 3rd party application like Wondershare MobileGo which allows you to transfer all media files from any Android device.
The choice is yours to make based on the available options.
