How to transfer my photos to PC wirelessly? I have an Android phone, and I have many pics stored there. Now I want to free up my phone space and transfer them to my PC. I don't want to use USB cable. Is it possible to do it wirelessly?
You cod use Google photos and the Google drive desktop app. Google photos will automatically backup all new photos (with unlimited storage as long as they are under a certain number of megapixels), and the Google drive app on you computer will load them onto your PC. 

And Google photos also has a button that removes photos from your phone if they are already backed up. 

Final bonus: you can now view your photos on your phone or computer, and you can also easily share them.
