Marigold, You can bring in the actual background image and poser will ask you if you want to change the window to the size of the image. Go to import > Background Picture and it will do the rest once you find the picture. Also, you can change the size of the poser window yourself by double clicking on the numbers at the top and putting in your own numbers like 800 x 600 or grab the little circle at the lower right corner and move it to the size you like.
