I just purchased the DSC-W200 and am a little confused about the pictures. I have the camera set for 12 mega pixels, but everytime I pause the cursor over the picture in windows explorer, the info window pops up and shows the picture to be 3 mega pixels or less. Am I missing something?

These are the dimensions of the images which can be taken :
4000 x 3000, 3264 x 2448, 2592 x 1944, 2048 x 1536, 640 x 480

It should be taking 4000x3000 at max resolution. Try fiddling with the settings again.

The picture size, does show 4000 x 3000, but still under 3 mega pixels.

Maybe you're confusing mega-pixels with megabytes?

It may be showing the thumbnail resolution, not the actual photo size. If you open the photo then right click and check the pixel size what does it say? hope this helps.

Ok, I tried it and this is what I get.

FILE
Type: ACDSee 6.0 JPEG Image
Size 3.3 MB

Image Attributes
4000 x 3000 (12.0 MP)
24-bit color 1 page(s)

I can see the 3.3MB & the 12.0MP, I being new at this, I don't really understand what I'm seeing.

Here's the low-down: 4000 times 3000 is 12 million pixels, or 12 megapixels. The "3.3 MB" is the space it's taking up on disk. You might assume that each pixel should take up three bytes, thus a 12Mpx image should take up 36 megabytes. You'd be correct, and if you save one of your camera's images as an 8-bit uncompressed TIFF file, you'll see it's true. But JPEGS are highly compressed, and that accounts for the much smaller size.
Still, a 3.3MB file out of a 12Mpx camera is pretty small. Make sure your quality isn't set to a low value.

Well, I have checked the manual and played with the camera, and I see no way to change the quality of the picture. It will let me change from 12M,3:2,8M etc....The only "Fine" setting is used when you record a movie with the camera. All the other cameras I have owned, did allow me to change that setting, but not this one.....
