We were talking about pictures, so they probably are in JPEG or TIFF format. PNG doesn't support EXIF but has textual [1] and timestamp [2] information. JPEG2000 seems to have something similar too [3]. If we had been talking about an article or some documentation, the binary resource would probably have been represented in MSWord, ODF or PDF, which support embedded metadata. If we had been talking about songs or audio interviews, the binary resource would probably have been represented in MP3, OggVorbis [1] http://www.w3.org/TR/PNG/#11textinfo [2] http://www.w3.org/TR/PNG/#11timestampinfo [3] http://www.jpeg.org/jpeg2000/metadata.html -- Thomas Broyer
