I have been reading up on the D80 lately. And I came across this website set up by Nikon Fans.
Imagine, a term coined specially for Nikon Fans -- Nikonians! 
Anyways, I was reading up on lenses and came across the term 100% crop image quality
I have no idea what that is. All I could gather is that is is some way to measure the clarity of the lens for a given configuration (eg 18-135mm, 18-200mm... etc etc).
Anyone here knows how to view a captured image at 100% Crop?
Please advise.

A 100% crop simply means to show a small piece of an image at its original size.
Often when sharing photos on the internet (especially when it comes to critiquing and reviewing) other users will ask to see a "100% crop".
Because images can be very large, when sharing on the internet, you usually post a smaller version. (If your original image is 30008x2000 pixels, you might post a version that is 500x332 pixels)
Well, in these smaller versions, you can't see the full detail, or what the image looks like in full size. Often images that are blurry at full size, look much sharper when you size them down smaller. (Have you ever looked at a small thumbnail of an image and thought it looked really good, only to open a larger version of the same image and see that it is blurry and out of focus?) So a 100% crop of part of the image will allow someone to view the detail you've actually captured.
Lenses with 100% crop image quality simply means that the images captured using these lenses are sharp, clear and full of detail... even when viewed at 100% full size!

This is a better explanation! Thank you so much trickiwoo!
Now I understand it a little better!
But then again, depending on the settings that are used to snap the picture (ISO, aperture speed, WB... etc), the picture given may not necessarily give the 100% accurate picture of what the eye sees, rite?
Given that the skills of the photographer makes the difference in the picture, if he knows how to compensate for the lousy lens, he still can get great pictures with a average lens. No?

a 100% crop is a part of the image viewed at 100%. I mean, the d80 has 10mp, right? so, 100% crop would be achieved by magnifying the picture at 100%, and croping a little area. It's basically a part of the image viewed at 100%.
