// based on an idea by Josh Gruenberg (joshgŘtwcny*rr*com)  //
// Can convert cached files from phpThumb() v1.2.4 and      //
// newer (v1.1.2 introduced caching, but the cached         //
// filenames weren't structured in a manner suitable for    //
// conversion until v1.2.4)                                 //
