Here is the deal man as I see it,understand it and have it working. Pictures are by default I think being saved to DCIM\100MEDIA if not in your case,then create a folder with that name in your storage card, go to your camera and set it to save pix to storage card. And you should be good to go no reg editing needed. I use Resco photo viewer and had that dilemma b4, so now they both point to the same location \STORAGE\DCIM\100MEDIA.
FYI: You can just rename your existing pic folder ...hope that takes care of your prob dude
