FW: Random Selection from TABLE

Hi,

I have a table that simply holds three fields:
    serial_id
    image_name
    image_text

I want to be able to select entries randomly so I can change the images on a
website using PHP.

Basically I need to have a randomly rotating image that will change whenever
the page is refreshed.

I want to store the image names in a table and have them selected from
there.

Using PostgreSQL version 7.1.3-2

Thanks
Kris
