#You can use this node to save full size images through the websocket, the
#images will be sent in exactly the same format as the image previews: as
#binary images on the websocket with a 8 byte header indicating the type
#of binary message (first 4 bytes) and the image format (next 4 bytes).

#The reason this node is disabled by default is because there is a small
#issue when using it with the default ComfyUI web interface: When generating
#batches only the last image will be shown in the UI.

#Note that no metadata will be put in the images saved with this node.
