The thing that confused me is that I thought zipping a file is in essence removing some repetitive or un-necessary data. Jpg is a lossy format because it does the same or similar function. I tell you I am easily confused at times. I do trust my friends! What is your preferred format for "default saving of images?!" 1.) PSD (PhotoShop) 2.) TIF 3.) JPG 4.) Other? Do you routinely save your images in pz3 format, as insurance? What are your reasons? Renderhawk. 1.) I often eat "dark bread," although I have a temporary craving for "Texas Toast" 2.) I don't drink alcohol much (long story) 3.) I drink 2% milk (close enough?!) 4.) I drink lots of natrually flavored sparkling water, and some juice. Thanks again for your wisdom, friends. Ron
