There are a variety of ways to view a bigger version of the BC. You can go here for a full screen version which will open in a new tab. If you are on a desktop or laptop you can drag the image out and it will automatically go into its own browser tab. You can also right-click the image and open it in a new tab and zoom in. Or you can hover your mouse over the image below and it will pop out into a larger image. When its like that you can click on the image and then scroll with the arrow keys on your keyboard. I don't know if you can do that on a mobile device.
