Nothing comes to mind. Although years ago, I used to have 4:3 aspect ratio images from a still camera. I need them all shrunk to 640x480 for use in Premiere, as they were put onto a video slideshow.
What I did was use the
Adobe Photoshop "web album" feature that makes web galleries out of image folders. I told it to make all my images 640x480, and I simply tossed the HTML pages and used the shrunk images. There were some advanced options available too, but I never really used them.
I found the feature by searching through the
Adobe Photoshop help file, as well as reading some documents on the
adobe.com site.
Maybe that helps?
