Import photo

This question has been asked before,how do I import only the photos I want.The answers are very confusing and I find windows gallery very hard to use.I clicked on import,box came up that gave me the device that was connected,pushed the next,bow came up with two choices,review,edit etc.and import all new photos.Chose this and it would import every picture that was on the camera.Why ? Tried a few times but with the same result.Now I can't even choose import all new pictures because it is grayed out.
