How do I get rid of the file name above the photo?

I really love this module... it makes publishing a photo gallery so easy... but, I would really like to be able to turn off the code that prints the file name above each photo. Is there any way to do this? My only other option is to change every photo's file name into something intuitive (like renaming a photo of my cat sleeping from "DS094278c.jpg" to something like "my_cat_sleeping.jpg")... and this would mean a lot of time renaming loads of files (which would not make for a very fun day).

Thanks.
