thank you jonknee, that makes sense. I implemented the changes you
suggested. One follow up question though. Since it would be absurd
to populate a file field is there a way to not overwrite the field
unless a new image is uploaded. essentially only activate the file
upload if somebody adds a file otherwise it remains as it was?
