Thanks for your replies guys. I really apreaciated. From what I read above I understood that to get my work on different res. I can change the resolution from Document Setup (double-click on render botton :)). I saved some pictures using this resolution: 1024x768. I also saved a picture with this res: 800x600 I know the difference between them is the quallity. But it is only the quallity? What I want to know is what are all the differences between my pictures on this different resolutions. I know that it's a very begginer question, but can somebody give me some infoemation here??? I would really appreaciate it. Thanks! cocoalex
