Plug your Razr into your computer via the included USB cable. A few seconds later pull down the notification bar at the top and you should see "USB Connection" and press on that. Select USB Mass Storage mode and press on OK. You should now see your Razr pop up as a removeable drive on your pc!
As for the stock gallery app, I personally like "JustPictures" and have a lot of success with it.
Please let us know how this works out!
