The correlation you should get from doing the Re(IFFT ....) is a one dimensional graph, whereas the max(max... you are applying is for a 2 dimensional matrix.
Try to plot what you have called im8 and see if you end up with a graph showing a peak.
When I try to access your image I get a message indicating it has been deleted or removed.
Sorry about your dead line, but it is Sunday here, and it is only just luck I caught this mail, as I have family responsibilities to deal with on a weekend.
Good Luck & Regards
