Actually, I believe it's the resolution size. A 800x600 picture will render smaller than a 1200x1600 render. The larger renders are good for things like making prints, and such but can be easily left-clicked, copied and printed without permission from the artist. It still keeps the same POV as the work-table picture you've been working on... just bigger. Then again, I could have completely misunderstood the question and be explaining all of this to someone who probably knows more than me anyhow. :) S'alright. Least I stopped lurking, XET Stormy
