I have recently re-installed Win7 at x86. An important database has been backup using "export database as SQL" function. Tested and worked under original Win7 x86 setting.
After the re-installation of Win7 x64, I have loaded the back-up file as SQL into the DB, but noticed the size of the database is 50% smaller compared to before. NONE of the JPG image in the DB after loading(out of 650 images saved in the database) is readable/displayable any more.
To test the issue, I have loaded a test image under x64 and read successfully using the same php code, which means the php code I have is fine and there is something right with the binary image text stored down. All text data are fine.
Please help to fix.
At the moment, I am going to try under a VM that build under Win7 x86 to retrieve to data.....
