Feature Request

[bla4free]

Thanks for developing such a wonderful application! I have one request--hopefully it's not that hard. Would it be possible, in a future release, to add function that can create unique file names for each upload? For example, if I already have a picture called "photo.jpg", would it be possible for you to automatically rename all uploaded files and append a unique number at the end? So "photo.jpg" becomes "photo-49fj29i.jpg"? Also, while doing this, could you make files URL friendly by removing spaces " ", commas ",", etc.? Thanks!!
