Yes you can. Depending which version of Photoshop you have, there are different ways to do a script.In 5.0 go to your actions palette, press the record button and then run through what you want to do with your particulaar images. When you are done press stop. Photoshop will have recorded every action that you did. After you have recorded the procedure go to "automate" under the file menu. Then pick "batch" and pick a action, a folder from, and then a folder to and let it go. Make sure you make a back up set of files "just in case" . It took myself a few times of trial and error's to get it down. Good Luck
