Thanks for your help.  Just in case anyone searches this in the future, 
I'll post my working code.  The key was loading the image using 
FXFileStream.  Also, removing the scroll area produced the same results:

require 'fox16'
include Fox

theApp = FXApp.new

theMainWindow = FXMainWindow.new(theApp, "Hello", nil, nil, DECOR_ALL, 
400, 400)
imagebox = FXVerticalFrame.new(theMainWindow,
  FRAME_SUNKEN|FRAME_THICK|LAYOUT_FILL_X|LAYOUT_FILL_Y)
imageView = FXImageView.new(imagebox, nil, nil, 0,
  VSCROLLER_ALWAYS|LAYOUT_FILL_X|LAYOUT_FILL_Y)
image = FXJPGImage.new(theApp, nil)
FXFileStream.open("gm.jpg", FXStreamLoad) {|stream| 
image.loadPixels(stream)}
image.create
imageView.image = image

theApp.create
theMainWindow.show
theApp.run
