Have you tried @Steve-Mcl example? Does it work?
Ya his sample for the it works I'm just trying to determine how to apply it to my expectations I guess.
clearly it doesn't seem to like me just passing in a sequence of image urls to a single image node though?
Are these URLs public? Post a copy and I'll do a demo.
Here is the flow I'm working with,

Yes they are public here are 3 for sample useage:
BG Image
Skin Image
Eyes Image
Probably a bit of a hack... but end result seems to work.

I appreciate the clarification on how this works, I was totally confused LUL
I think i understand the jist of this now.
Presumably i can just pass the final node to a file write node to produce my final file I think can manage from here. I'll leave this thread open for a day though just incase 
Thanks for the help!
Not a hack at all - you kept everything in series (to prevent msg cloning).
Only things I would do differently is load images first and use blit instead of composite as blit is faster (it doesnt try to merge pixels (it just overwrites them))

Yes if you change the last node to output a buffer & connect it to a file out node.
Alternatively, you can use the built in write function...

I see that you said this would be the faster way to do this, what do these guys look like inside?
Here is my version of that flow...
