Hal,
I see now that Fractint v 20.0 can natively create large images directly in Disk Video mode. From the docs:
"New 32767 x 32767 (32K) pixel limit. Removed the 2048 pixel limit for the size of fractals. You can now define disk video modes larger than 2048 x 2048."
Try selecting a VESA graphics mode, then go to the <v> screen. If your graphics card supports it, you should be able to create images up to the limit of your graphics memory. The limit for using expanded and extended memory in disk-video modes under windows is limited to 16 MB, the max the pif allows you to allocate. Once the image is beyond this size, your hard disk will automatically be used. You can watch what is being allocated in Fractint by starting up with the command line option debug=10000. Jonathan
