I use Photoshop Elements 7. It has a batch process option.Before I start I create a folder to down load them to so they don't overwrite the original. Once you hit the batch process option you will select the folder that holds the pictures then select the folder the process folders will go to. You can set the size you want. I typically use 800xaspect ratio at 300 ppi which will limit the print size to something like 2.**x2.** inches.If you want the folks to be able to print what you send them then change the 300 ppi to something lower like between 72-150 ppi.I also save as the highest jpeg setting put you could do it lower and save some kbs. You can also add a water mark to the photos if you choose to or a caption.
