Metadata Record Sets

[Darius1968]

If I acquire a jpeg image(s) from the internet via Firefox, they don't already contain the full xmp/iptc record set.  For instance, proper jpegs from a modeling agency, for instance, have fields for headline and caption, and these aren't to be found among images gotten from the web.  So, how can I 'import' such a record set into the said image(s)?

This is either IPTC or XMP metadata.
IMatch adds this data to your files when you edit the data in the Metadata Panel and the Keyword editor.
You can copy data from other files into the downloaded files.
You can use Metadata Templates to fill in metadata.
