As simple as this may sound, have you cleaned the lens lately? A lot of image quality deterioration comes from a finger print or other smudge on the lens. Digital cameras are succeptable to even the smallest gunk on the lens. Because the lens element is very tiny, use a cotton swab with a drop of lens cleaner (or isopropyl alcohol) to thouroughly clean and dry the lens. If it isn't a dirty lens, check your file-size and flash settings.
