Yes, the images are not copy protected in any way and are yours to do with as you please. You can create a slide show, edit the photos, reorganize or rename the photos.
We recommend also uploading all of your newly scanned images to a photo sharing site as a cloud backup. This helps redundancy should something happen to your computer's hard drive or the DVD become damaged. If the images are stored on a site such as Flickr, you can simply re-download them.
