You got me confuesd: DPI = Dots Per Inch right? So as the Dots are smaller the image is better. Though it does not matter for the web, unless your picture must be perfectly accurate so you can make a big size of it, am I right?

For printing matter the dots should be more densed for better quality disregarding the actual size (width & height) of the image.

So... if I work on the web, why dpi does not matter? If I have a 1x1 inch square with 1000 dots in it, compared to the same square with 10,000 dots in it? It does not make any sense to me.

Logic says: In the same size (width & height): MORE dots = BETTER quality = MORE space... http://www.talkgraphics.com/images/smilies/confused.gif
