Download

Registration 

is not required, but I would enjoy knowing who used the software.  No spam. 

Install

Download: imlook4d (version 6.1.6 -- then update, se below)

Install:  Unzip, and add to Matlab path ("add with subfolders", see instructions)

Run:  Type   imlook4d   at the Matlab command prompt


Update

Later releases of Imlook4d can be updated using Update in the imlook4d HELP menu

SPM and ImageJ

imlook4d can also integrate with features from external softwares.  This is not the basic use case.  In case these features are of interest, you need to download additional softwares:
