Bumping because it seems to be a hot topic due to the May challenge. I've also made it sticky so that it will be easier to find in the future.
I really must say that while the most information on the linked page is correct he doesn't get it all correct.
Here's some links to Wikipedia that's relevant:
http://en.wikipedia.org/wiki/Dots_per_inch
http://en.wikipedia.org/wiki/Lines_per_inch
http://en.wikipedia.org/wiki/Halftone
And here's an alternate way to describe dpi, ppi, and lpi. IMHO a more accurate than the photo guide above:
http://desktoppub.about.com/cs/inter...resolution.htm
The thing is that higher resolution does not always increase the quality of the printed image and in order to keep the image size down (in mb) it's better with as low dpi as possible but still high enough (about two times the lpi).

A bit of thread necromancy.

Is another discussion on this which reiterates my own opinion that DPI only matters when printing and should be abolished otherwise
