It's a three year old thread and the images were uploaded to a third party site so they have probably been deleted and you don't need to see the images to import the attached statistic into PokerTracker 4:
1. Download the custom statistic posted in that thread.
2. Extract/unzip the custom statistic from the .rar file.
3. Import the extracted custom statistic (.pt4 file) into PokerTracker 4 (File -> Import Statistic).
4. If you need the statistic for cash games (it was written for tournaments) convert it via the 'Options' button in 'Configure -> Statistics'.
5. Create a custom 'Player Report' in 'My Reports'
6. Add the custom statistic to your report.
