Conversion of thumbdata3-1763508120 files to jpg file format

As far as we know, no way exists how to get a JPG picture out a THUMBDATA3-1763508120 file. It is just a cache file that contains thumbnail data for a picture that exist, or once existed in your Android phone. The problem is a .thumbdata3-1763508120 file contains data from ALL pictures, not just single one, so there is no way how to get a single one, even in thumbnail form.
