i downloaded xnview 2 years ago, , added title/subject/keywords metadata bunch of jpegs. compared keywords xnview , adobe bridge. realize different. believe title/subject not same. noticed this, because stock photo agencies not read metadata xnview. leave title field blank. looks xnview uses xmp format whereas adobe uses iptc. suggestions on how can batch convert
does adobe software support iptc metadata these days? authors of xmp competing standard, wonder. also, see https://en.wikipedia.org/wiki/extensible_metadata_platform#support_and_acceptance list of software can check actual content of metadata particular file (i suggest http://owl.phy.queensu.ca/~phil/exiftool/ versatile option).
