Ordo:

Ya can use PHP.. probably better.

Here's "similar" using SSI - just do a query string..

yourdomain.com/someplace.htm?999999

someplace.shtml?some-affiliate-code-here

(no need to use an actual .shtml - edit your server httpd.config or stuff an .htaccess hack to get it to parse .shtml pages as .html's etc)

Inside your gallery pages use this:-

whatever.com/< !--#echo var="QUERY_STRING"-- >

(kill all space in that query string at start and end)

The SSI doc will echo whatever variable you tell it to.
