Subject Re: reader implementation ideas ?
Date Mon, 04 Jul 2005 22:01:01 GMT
In the case of photography, Jpeg cameras embed a 120x160 thumbnail in 
the file. Look up the 'EXIF' standard.
In the case of artwork, you can't be certain that the thumbnail is 
consistent with the full image.

Clients virtually always want the thumbnails along with the meta info.
