Hi I had the same problem with a background I created in bryce. I may be wrong, and no doubt someone will correct me, but I think that even if you increase the resolution of an image you will not necessarily get an increase in quality, in short you cannot go beyond the quality of the original image. I think that there are image enhancing programs/plugins avalable which use some sort of fractal 'magic' but where off the top of my head I couln't tell you. hope this helps If not I'd sure like to here the 'real' answer Dave
