As per Graham above.
I have had some wine now so excuse if this doesn't make sense to man nor beast..
Photomechanic (often referred to as PM ) costs about £95. If you are serious you can learn how to use it at home and how to add IPTC data, how to ingest photos in to it etc.
Look here on Camerabits youtube page (Camerabits make PM)
https://www.youtube.com/user/CameraBitsInc
But as Graham says you should ask your friend to show you as it will be far quicker to learn that way.
However to get you up and learning you can download a 30 day trial of PM from here
http://www.camerabits.com/downloads/
Then download from my dropbox 4 files. actions.txt, Charlton Athletic.txt and Leeds United.txt & Charlton Athletic vs Leeds test.xmp from here
https://www.dropbox.com/sh/h5ksmz2fzq61mub/pjJQyzp6nH
Then load up PM and click Edit > Settings > Set Code Replacements. Click Add, then one by one load in the 3 .txt files you downloaded from my Dropbox & click OK.
Then in PM click Image > IPTC Stationary Pad, then at the bottom click Load and find the Charlton Athletic vs Leeds test.xmp then click Open and then Close Stationary.
Ok then click File > Open Contact Sheet and find a folder that you have some images in.
Then click Ctrl+A to select all the images, then click Ctrl+I (which will bring up the IPTC Stationary Pad), the click at the bottom Apply Stationary to Selected.
Ok now your images have a base IPTC applied.
On your first image, move your move over it and click on the I.
You should have a flashing cursor in the top box on the left. if not move your move there and click.
The type the following \c4\ \v\ \l21\ and press your space bar. It should now read as
Charlton Athletic's Johnnie Jackson vies for possession with Leeds United's El-Hadji Diouf
The \c4\ \v\ \l21\ comes from the actions.txt file that you loaded earlier. You can edit this all you like to words/phrases that you/your agency like.
There you go, you have now added IPTC and code replacements to an image.
Then click Ctrl+N and this will save the IPTC to that image and move on to the next images.
So your challenge is figure out how to Ingest images in and apply IPTC on Ingest.
i.e. Most people on here are happy to help as long as you are willing to learn and that you are also willing to learn things by yourself with some guidance.
I hope that is helpful. Please let us know how you got on and when you can ingest photos and apply IPTC from your memory card.
