I’m not sure it’s practical, but has anybody every thought about using existing EXIF tags to determine image resolution?

AFAIK, both JPEG and TIFF support EXIF tags (http://www.w3.org/2003/12/exif/) and thus embedding of resolution metadata (Labels: resolution, xResolution, yResolution, resolutionUnit).

There could be another special tag @exif (or @native, to avoid being tied down to one particular way of embedding info), which basically means: check the embedded resolution info.
