Why can't my computer download my gallery?

[AC Question]

My computer says there's no photos to download. When I look at the picture folder, it's empty. But my gallery has forty pictures in it.

do you unlock the phone before connecting to your computer?

After you connect the phone to the computer, you need to unlock the phone's security screen and accept the connection from the computer.
Also, make sure the phone is in MTP mode for the USB connection.
