This project currently uses Python2.
This project was originally created to extract JPG's out of the Android Thumbdata3 format.
It is theoretically capable of extracting data from any file that contains multiple JPG's within.
Usage is quite simple. In the following example, the filename is simply thumbdata3
:
./extract.py --file thumbdata3
The script will then output all JPG's to the same directory. These are the files you are after, named sequentially.
