I am making posters at 20"x30" for my photo business, and have made a template of this size. I have added photos (large files) and some graphics, and now my computer runs very slow. New Dell Laptop with Vista, 1gb of memory. My questions is, should I resize the template down to a 10x15, or 5x7.5 so that it is not as large, then resize it up to the 20x30. WIll I lose print quality. Just looking to have the computer run faster in my design. Any help would be great. Thanks.
