What is the use of a book without pictures?

Since the last post I've worked on the screenshots feature. There was few requirements:
1) During the recording process screenshots should record into the same file as other evetns
2) It should be possible to setup period of screenshot recording
3) During the playback process screenshots should read from playback file and compare with current game screen. Best of all it would do using MD5 hash, so it must be recorded with image data.
