That's exactly right! A lot of images can be blown up quite large, if they are meant to be viewed from a bit of a distance. I made a 6-foot wide print of an owl, from a 20 MP image that was cropped to about 10 MP, and I have to say it came out great. If you look at it right up close, of course it's a bit fuzzy, but you can't appreciate the image unless you're standing back so it really doesn't matter. On the other hand, a friend of mine who is a pro has a spectacular landscape shot that has all kinds of detail in it. It's meant to be appreciated both from a distance and also from up close, so it needs incredible resolution. He shot it with a medium format body (I'm guessing 50 MP), so he can blow it up to 8' wide and it's still absolutely tack.
