When I try this script with any other image it fails when loading image from data base, am I missing at setting some where?

Can not use images with large sizes .. Because the SQLite library can Readings only a specific size at each time

This code is modified you can update the data in the database

#include <SQLite.au3>
#include <SQLite.dll.au3>
#include <WindowsConstants.au3>
