they can, if we specify the image format in dedicated IPTC tag.

look here :

https://projects.kde.org/projects/kde/kdegraphics/libs/libkexiv2/repository/revisions/master/entry/libkexiv2/kexiv2image.cpp#L864

none JNG or PGF are registered in Iptc.Application2.PreviewFormat.

look format list given by exiftool by tag "ObjectPreviewFileFormat" :

http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/IPTC.html

We can registered new value as 100 or 1000 with JNG of PGF to be sure to not be
in conflict with another one.

Note : why not to migrate preview data from IPTC to XMP now, exemple into
digiKam namespace ? We can do what we want into it (:=)))
