Hello, everyone! I'm new, thanks in advance for any help you can provide me

I just bought a new Sony Cybershot 330 today, took a bunch of great pictures, and when I plugged it into my computer and uploaded the shots, they show up as mere icons, such as a green play button symbol or other animated icons from the camera. The photos themselves are nowhere to be seen.
The only thing I can fathom is that the new camera is 14 megapixels, and my computer is 3 years old, so maybe they just aren't compatible somehow? I have no idea. Can anyone tell me what the problem might be, and is there anyway to get photos from this camera onto my computer without buying a new computer??
Thank you!
