I'm still seeing a lot of people posting pictures with missing metadata. Some are intentional, but most users don't know there are nodes which allow to embed metadata into the picture.
I recently discovered a node which has changed my life. This is not the first node I'm testing and using to save metadata, but this one is the best to me so far.
In the end, no more hassle to connect or update the node to get the matching metadata for civitai!
TLDR
Use SaveImageWithMetaData node instead of your old node to save your image:
https://github.com/nkchocoai/ComfyUI-SaveImageWithMetaData
Explanation
It's been around for a few months, the SaveImageWithMetaData node allows me to save automatically info about:
the prompt
the checkpoint
the cfg
the seed
the LORAs
the sampler (except on my flux workflow)
the scheduler (except on my flux workflow)
The first feature I appreciate a lot is I only have to connect a "latent image" as an input to the node.
The second feature I appreciate is that loras are included into the metadata, even though I'm using the Lora Stacker node. That's really a relief for me!
Finally, this node save the metadata faster than the other free nodes available to my knowledge.
Btw this is not new, but you can use variables in the filename_prefix such as %date:yyyyMMdd_hhmmss% to write the date and time in the filename.
