Nextgen Public Uploader - connect with WP username?

Hi - I'm using WP 3.0.1 and Atahualpa 3.5.3. I have installed the NextGen Public Uploader which allows users of my site to upload their own photographs to my site...those photos then go into my NextGen Gallery. The problem is that there is no connection between the user information data stored via the WP login (I.E. username) and the photo that gets uploaded...in a nutshell, I have no idea who submitted the image. Does anyone know how I could make this connection? Is there any code I could add that would give me this functionality?
