Need some help using iPhoto on my Mac

[HDMan72]

I can not figure this out, it seems so easy but here is the problem. I connect my Maxx to my Mac using a USB cable, Maxx is connected as mass storage. In my Finder of the Mac, the Maxx is mounted. iPhoto than opens up for me, under devices I have Mot & Mot 1. In new photos inside iPhoto it says loading, but they never show up. Import Selected and Import 0 Photos are not highlighted nor can be. I can't figure why iPhoto does not see the photos on the Maxx. Any help would be appreciated. Thanks!
