Thanks for the info Mark,
yes I was already aware of the contact sheet maker feature in Photoshop.
however the script i was refering to is so much more, you can copy and paste from the thumbnails into the quark doc you are working on. and then mark images that have been used (very useful for long books etc).
I have subsequently foun the and downloaded an updated version of the script from this thread:

I am still having trouble with it running on mi iMac G5 10.4.5
it works fine on my iMac G4 10.3.9
just a minor annoyance now, saves me 4 hours work per book anyway!
Thanks again for the contribution Mark,
