I ran into this problem before as well. There is a very simple fix (until NI fixes the problem natively):
Upcast your image display reference to a generic LV control reference
(using the "To More General Class" primative) and then pass that
reference to your subVI. In the subVI, cast it back to the image
display reference (using the "To More Specific Class" primative).
You should then have access to all the properties and methods available
for your image display, including the ability to update the display
with new data by wiring an image reference to the "Value" property
node.
