Love the phone, but having trouble copying photos from my pc to the correct directory on HTC One. I have tried the software that comes with phone and it imported music just fine, but not photos.
You can use an app like ES File Explorer to copy and paste them to your phone over your local network, or an app like Air Droid to do the same but via a web interface from your PC's browser. You can also hook up to phone to your PC via USB and copy/paste your photos to your phone using Windows Explorer ... your phone should show up as a removable drive in Windows Explorer when connected to your PC via USB.
