It didn't use to be a problem when it was Your Phone (or whatever the app was called). I found a fix that works on my Samsung since I couldn't make the other suggestions work.
First create an album on your phone to move the pics into. Then connect a USB cord from your phone to the computer. Phone shows up in This PC just like if you put an external hard drive, flash drive, etc plugged into the desktop. Internal Storage. DCIM. Whatever album folder you put the pics in. You can open it up and select all your pictures to move to another source.
