Image resizing AND changing resolution with Automator

[woolybully]

I've read the posts on image resizing with Automator & have done this successfully. However, my large images start at 314 dpi and are resized to small images at 314 dpi. Is there an Automator action I'm missing that will also change the resolution to 72 dpi for web viewing? Or is there another way to batch this job?

Thanks,
Bob Kruse
