   DPI has nothing to do with resolution.   
   If you've seen images that are horribly pixelated, they could still be    
   2400 dpi.    That just means that the image is using 2400 dots in one    
   inch to represent the picture.   And that 2400 dots could be 240 big    
   square looking pixels that are 10 dots wide each. So you have a    
   collection of 10x10 colored squares in the image and that's what makes    
   it look pixelated.   
       
   I can take a really grainy picture and change the DPI and scale the    
   image larger to make its size mega pixels in photoshop, but the picture    
   is still grainy or pixelated.  "You can't get blood our of a rock".
