Any one know how to display, go to page number on a record list page

Prev 1|2|3|4|5|6... Next
Here's a very simplified demo of dropdown+arrows paging code I did for my
gallery software.
It might not be the most clever code around, but it works, and scales well.
All you need to edit is the main query, couple fo arrow images, and
database connect code to make it run. It now feeds itself, so you might
want to change that, too.
Live demo is e.g. http://photography-on-the.net/gallery/list.php?exhibition=1
