same here... I have a 17" monitor at 1024 x 768. So a document size of 800 x 600 works just right on the Bryce screen. For verticle pics I'll usually work at 450 or 500 x 600, just so everything fits on the Bryce workplace. Then when it comes time to render, I'll render at 1:1.50 or 1:2.00, especially if I'm going to do any post-work liking painting on the image. (easier to paint on the larger image). To put it on the web, I use Photoshop (personal preference) to compress the .bmp to .jpg and resize it back down to original size to post in the forums here. Sometimes a full-size version will go in my gallery. You'll have to play with and get to know whatever graphics program you use to convert to .jpg to get what you feel is a good balance between file size, image size, and image quality.
