I've found out the problem:

It's Kodak EasyShare my brother put on, that's what's stuffing Windows Explorer up, just currently looking at the Kodak site. Kodak EasyShare associates itself with the .jpeg files so that must be the conflict.

Weird, but, it's for real (it's true).
DC5000, DC3400, DC280, DC265, DC260, DC240i, DC240, DC220
To use your camera with WINDOWS XP Operating System, do not install the software that was shipped with your camera. WINDOWS XP Operating System comes with drivers that will allow you to connect to your KODAK Camera and take advantage of the EASYSHARE System. Download and install for free the latest KODAK EASYSHARE Software.
After you install the software, connect your camera to your computer. When you are prompted to select which application to launch, select KODAK EASYSHARE Software. Also check the box that allows EASYSHARE Software to always be the application that launches when you connect your camera.
^ Wonder why.
Thanks for the help anyway guys.
