Arduino PTP USB Library Modification

I need a freelancer to make a simple modification to the Arduino PTP library (the pull request). In my scenario the Nikon library works fine, but what I want the library to do is to return the image filename when an image is captured. So for example you call the library (something like [login to view URL]()) and it would take the photo and it would return the captured filename which I would store as a variable. This is a fairly cheap project, will no doubt be a simple one. The library is here: [login to view URL]
