💾 TOO Smart Image Saver

Here's a ComfyUI quirk that surprises people who post to Civitai: the default SaveImage node writes the workflow graph into the PNG, but it does not write the flat A1111-style parameters string - the one Civitai's uploader scans to auto-link the checkpoint and LoRAs by hash. So your uploads on Civitai show up with the model blank. TOO Smart Image Saver is the fix: it writes both the ComfyUI workflow and an A1111-compatible parameters block, plus filenames you actually control. It's the "swap out your save node" move, in one node.

How it works

The node builds a filename from parts - prefix, extra1, extra2, model, suffix - joined by a separator, all supporting date tokens (YYYY, MM, DD, HH, mm, ss, timestamp). It writes into ComfyUI/output/<output_folder>/ (the default output_folder is YYYY-MM-DD, so you get date-bucketed folders for free). Then it saves and stuffs metadata in:

• PNG → A1111 parameters as a text chunk, plus the ComfyUI prompt/workflow chunks.
• WebP/JPEG → A1111 params in the EXIF UserComment, workflow in Make/Model tags.

The metadata input (METADATA, typically from TOO's Image Metadata editor) supplies the positive/negative prompt, seed, steps, cfg, sampler, model name and Model hash, and Lora hashes - which is exactly the shape Civitai parses. If you leave it unwired, it writes the workflow and skips the A1111 block.

The inputs you'll actually set

There are a lot of widgets, but the ones that matter:

• images - required, what you're saving.
• output_folder and prefix - the filename skeleton. Default prefix ComfyUI_YYYY-MM-DD_HHmmss is fine; most people just add a model and a suffix.
• model - a plain string. You type the model name (or a path); the node strips the directory and extension and uses the clean basename. Hand-typed, not auto-extracted - the sibling Advanced saver does the auto-extraction from the graph.
• output_format (default webp), quality (default 97), webp_lossless - the format knobs.
• save_metadata and embed_workflow - both on by default; flip them off for a stripped file.
• Optional metadata and workflow inputs to inject A1111 data or override the embedded graph.

Outputs: images (pass-through - you can keep processing after saving) and filepath, the path of the first saved file.

Install

Same as the whole pack:

cd ComfyUI/custom_nodes
git clone https://github.com/tetsuoo-online/Comfyui-TOO-Pack

restart, or install via ComfyUI Manager by searching "Comfyui-TOO-Pack". Dependencies are torch, numpy, Pillow and piexif; nothing extra to download.

Common issues

• The README doesn't match the node. The README's "Smart Image Saver" section describes fields like seed_node_name/model_node_name that target nodes by class or #ID - the shipped TOOSmartImageSaver doesn't have those widgets. That's the Advanced saver's job. On this node the filename comes from prefix/extra1/extra2/model/suffix. If the README confuses you, trust the node's own widgets.
• JPEG metadata goes missing for big workflows. EXIF has a 64KB ceiling; the node hits it, drops the workflow, keeps the A1111 params, and logs a warning. Save PNG if you want the whole graph to survive - it's also the only format that round-trips a full workflow anyway.
• webp_lossless ignores quality - lossless is lossless, and the files get heavier. It's a deliberate trade, not a bug.
• --disable-metadata (or the "Disable saving prompt metadata" server setting) turns metadata writing off globally; this node respects it, so don't hunt for a bug if you've set that flag.
