I am a recent Mac user and there is one thing that is bugging me. In Windows, if I wanted to view all the pictures one by one in a folder, I'd just double click and Windows Picture Preview will launch and you can hit the left / right arrow keys to go to the other pictures. In the Mac side, to achieve this, you have to select every picture file for you to be able to hit the right / left arrow keys to advance. You can't just open one picture and have it open everyone in the folder. Anyone know how I can make this work?
