Than you. I really am puzzled. I downloaded the locked zippyshare version of the map. Size of img file when unzipped is 3690432 KB. After processing by FastIMG unlocker, the IMG file = 2632832 KB. The sizes are as shown in Windows explorer. The IMG "works" both in my Garmin 62s and basecamp. I am also puzzled as to why you -and others - can unlock the IMG with gimgunlock whereas I cannot. Do you have any thoughts on why I should be getting a smaller IMG file after using FIU?
