Amazon affiliate - display random keywords items?

I have an amazon affiliate ID. I want to display the right books depending on the page I am on.

How can I do this. ideally, a random 3 books from a keyword based list would be perfect.

Anyone know of a free script for this ?

thanks

Here's a link to one that's good for php, http://www.chipdir.nl/amazon/ . It's pretty easy to use if you know php....you can edit the search string with a php variable (in your case, the page name) and it should work pretty well for that.

cgchris, hey, I actually know of a perfect script for you if you haven't found one yet.

There is a script from this company called sooksoft found at http://software.sooknet.com, they have an amazon affiliate script that can do exactly what you are talking about doing and its available for the us, canada and uk. I've played around with it and its just a script in an iframe that sends the request to their server, you can change the query being sent to the server dynamically through some variable on your end and you can specify how many products you want sent back from 1-10 which sounds like something you might need.

Anyways, I hope that helps.
