OK, in some sort of JPEG metadata (I'm not familiar with this, but  
wonder if ImageMagick lets you control it) the first says "250 DPI"  
and the second "72 DPI".  If you are on a Mac (maybe Leopard  
necessary) you can see the effect by opening in Preview, then in  
Preview's prefs toggle the 'Images'
| 'Default Image Size' option back and forth.

Emacs.app currently respects the DPI.  Perhaps it should be changed to  
ignore it?  (I don't like the idea of an option, unless other  
platforms could be talked into supporting it.)

-Adrian
