I think the easiest way is to put all of the images in one folder on your desktop. Then open Photoshop, then click on FILE, then BROWSE, open the folder,(this should open bridge automatically) then select all (CONTROL A), then click on TOOLS, the first icon is BATCH RENAME. Click on that and then under NEW FILENAME select SEQUENCE NUMBER.
Pretty easy if you are using Photoshop CS2. Email me if you need more details. By the way, I'm using a PC, so MAC commands may be slightly different.
