Image Gallery Displaying Duplicates of Every Photo

So I’m using the Photosmash plugin to create a photo gallery for a client’s website. For some reason, all of the pictures are being duplicated in the image gallery. They are not being duplicated on the backend where the client can moderate guest images. Can someone please take a look at the site and let me know if there’s anything I can do to resolve this issue?

I know that Photosmash has been essentially discontinued, but it’s perfect for what this client needs.
