I was always confused about DPI when it comes to images (versus print).  I 
thought, it's all about (w x h) resolution, not DPI, right?  I found this 
page to be informative (and funny) http://www.dpiphoto.eu/dpi.htm.

So basically, I simply scale the image larger right?  Perhaps double or 
triple the resolution of "b.jpg", right?
