Re-Sizer – a Photoshop Action Pack – was specially developed for enhancing photos and images from low to high quality. It claims to enlarge the size of photos up to 600% without the loss of quality, and apparently this little Action Set is legitimate. Getting best results with stock photos, in our estimate, it has the potential to save agency designers hundreds of dollars. Not to mention oodles of time if they can work more effectively with stock photo comps. Pretty cool demo site too.
