well after many months of on and off at this script it works, minus the fact it doesn’t have the save options-- but I decided to share anyway since some people might need this::
it scales the images and then adds a padding around it by resizing the canvas
you can modify it so you can scale a set size of images and have a final output for large web production

right now it works in Photoshop CS3 on a pC, it should work on a mac since it uses javascript
