Help with Adsense 'Keywords'

[Citibroker]

Dear all

I have implemented Google AdSense into my website www.reppel.ch but can't figure out where I have to place the relevant 'keywords' in order to get the relevant ads displayed below my pictures. I have already tried to add keywords to the album description and album keywords (by editing the album) but had no success so far. I have searched the forum intensely but haven't found a detailed guidance 

Can anyone help?

Thank you very much; you are doing a great job here!

Add relevant category and album descriptions. Add relevant file caption and description. Apply the changes suggested in http://forum.coppermine-gallery.net/index.php?topic=37258.0 if you know your way around
