Is there a program or piece of software already on pc's that can resize lots of digital photo images in one go, if so what is it and how do you do it? Want to upload a lot of images into some albums but want to reduce the file size to upload quicker and they don't need to be the original size. If I do one I usually resize it in photoshop and save it as another file rather than lose the original but it's a right faff to do that to a 100 or so, what can I do? Ideally just copy the one's I want, resize all of those and upload those ... how?
Thanks
