Thanks for those links. That Google parser is read-only, but its 
documentation looks useful.

Just now I thought to look at Apache Commons and found the Sanselan 
package, which does a similar job to the javax.imagio.* stuff but as a 
free-standing package and, unlike them, it includes EXIF read/write 
abilities. 

Its interesting that all this stuff is about the same age: Java 1.4 or 5 
and none of it seems to have been updated since. Maybe, since nothing has 
changed in the JPEG/TIFF worlds since then it hasn't needed any updates, 
though as its all decidedly light on documentation, some changes there 
would be nice for those of us who don't understand the structure of image 
files: another common thread in all these packages is that the authors 
all appear to assume that everybody is an expert on image files and their 
contents.
