One little task for you. In Keyword List, right click one of the keywords that's failing to export and ensure Include on Export is unticked.
Yes John, it was 'unticked'. Then I 'ticked' it, exported the photo and voila, the keyword was exported.
BTW I'm working with a Mac and have LR 5.3
I'm very pleased by all the help you guys are giving me
Thank you very much!
To make things perhaps a bit more clear... In the Image Info Toolkit I select the word which is at the end of the chain to a window in that program, then I select them all copy and paste them in the key wording area in LR. I'm doing it now, just to show you what the result is with the keyword 'Dog Canyon'. I paste it now in this post so you can see how it shows up in LR.
Dog Canyon,Oliver Lee Memorial State Park,New Mexico,North America,United States of America,Alamogordo,USA,U.S.A.,Amerika,America,SP,State Park,Oliver Lee,NM,US,U.S.,United States
You see, it's just comma separated tekst. Nothing under the hood.
I will now backup the catalog and install the script.
When that's done I'll be back.
