Resolution poor

[mtamocon]

I took a bunch of pictures yesterday with my Panasonic FZ18. I used the RAW + Jpeg mode to save onto my card.

When I open the RAW image in CS3 here's what the spec's are;

16bit, 3264 X 2448, 8Mp, 300 ppi

I then open the image. Here's the issue.... If I zoom in just once I can already see some pixelzation. The more I zoom the worse it gets. I thought it might be a monitor problem so i cropped it to an 8x10 and had it printed at Wal-Mart. Didn't look too good. I have taken other pictures and printed at 18x24 and they look pretty good.

Anyone have any idea why this is happening? Anything i can do? Any help will be greatly appreciated!!

Take a photo of what you are seeing and post it here (upload image to tinypic.com, copy/paste IMG code).

The point is that everybody has his own idea about, I quote:
