[Plugin: NextGEN Gallery] How to display filename on NextGen using Shutter Reloaded

As title, I am curious how to go about displaying the filename when using Shutter Reloaded for NextGen. The place i want to display the filename is when user click on the thumbnail and when they see the full-size image. Perhaps showing the filename next to the arrows and next to “Image x of xx”.

Any help appreciated in advance
