It indeeds gives conflicts because you have used in your clone the same node identifier as the original node.
BTW a few months ago, @dceejay and I have been pimping the original node-red-contrib-image-output node quite heavily:
- it also accepts jimp images
- it automatically resizes images to the size they will be displayed, to reduce data traffic
- it has a button (similar to the debug node) to pause the image streaming at server side
But it is indeed a pity that now both nodes can't be installed together, because I want to use your image-tool nodes and the original image-output node. But don't know how to achieve that...
