I would find it helpful if I could freeze a File compositing node:
https://www.sidefx.com/docs/houdini/nodes/cop2/file.html [www.sidefx.com]

i.e. like the way you can freeze a geometry file in read mode.
Otherwise I have to archive the directory structure of my houdini project to include the directory containing the image file, with file paths relative to hip.
I'm assuming others would find this useful?
thanks
