With the help of Scott Spearman I found this

$ identify -verbose *.jpg | grep -E '^Ima|Geo|Res|Uni'
Image: bugzilla_add_patch.jpg
   Geometry: 800x600
   Units: PixelsPerCentimeter
Image: bugzilla_choose_product.jpg
   Geometry: 800x600
   Units: PixelsPerCentimeter
Image: bugzilla_enter_bug.jpg
   Geometry: 809x588
   Resolution: 95x96
   Units: PixelsPerInch
Image: bugzilla.jpg
   Geometry: 800x600
   Units: PixelsPerCentimeter

As you can see sometimes (bugzilla_enter_bug.jpg) jpeg file have the
"Resolution" info.
