I got this reply on the ebay photo forum! i think I've got it now! woohoo!!!
A couple of different ways to achieve this:
1. Download Irfanview. Free program with an easy-to-use batch process that can resize all your pics at the same time. Use the rename feature to preserve your originals, and drop the resized pics into a new folder.
www.irfanview.com
Determine the "output" folder and the originating folder, set advanced options to resize and rename, and click OK. This free program is fast and easy.
2. In Photoshop, click on "File", then scroll down to "Automate", then "Contact Sheet II". This feature will take images from a folder and create a multi-photo contact sheet. You can determine orientation, how many rows and how many columns you want to have based on paper size, and quality. With a little calculating, you should be able to approximate 2.5"x3.5". If you want to be exact, use "Automate" and look for the "Batch" process. This is similar to the one in Irfanview and will let you resize entire folders easily. Once you have created your contact sheet(s), you can simply print those pages with all your images on the same sheet.
3. Another way is to record an action where you must perform the steps you wish the program to repeat. This will be slower than a batch process.
