Thanks, Herbert, but renaming the image to von-neuman.bmp didn't make any difference. Here is the part of the file that makes a problem...
ok, I see. You put the graphic into the caption, named with the label FIGURE#. Always hit enter and put the image before this caption line. see attached file (click on the image to insert this one new to get the right path)
