I did not know you could import an image file.
------------------------------------------------------------------------
The best way to do this does not require messing with CSV file. What
you do is download from the source radio and save the tab to a CHIRP
Radio Images (*.img) file. Then you download from the target radio. If
you haven't already, save a copy of the target radio to a CHIRP Radio
Images file as a backup. Then Import the CHIRP Radio Images file into
the tab for the target radio. Make any other settings changes and
upload to your radio.
This page explains how to do it between ad UV-5R and a UV-82.
