With the recently introduced FilePart in IIP our implementation works only with the legacy switch on imgcat:

imgcat -l addons/addon-image/fixture/palette.png

The chunking in several sub sequences was introduced to overcome a limitation in terminal multiplexer like tmux. We should extend the IIP protocol to also support the sub sequence chunking.

Edit:
There are various changes needed for IIP on top of that, see jerch/xterm-addon-image#57 and jerch/xterm-addon-image#58.
