Save Image(Eclipse Suffix-TJ)

Save Image (Eclipse Suffix-TJ) is the variant save node in TJ_NODE's "Eclipse" family - the branch of the pack that's built around keeping original file structure and metadata alive through a processing chain. Where the plain Suffix save keeps the pipeline's naming, this node is for when the original image came from somewhere real (a dataset folder, an Eclipse workflow) and you want the upscale or detail pass to land next to the original, keeping its relative path and metadata story.

What "Eclipse" means here

Eclipse is the ecosystem of image-processing workflows where you track images by their original source path rather than by ComfyUI's auto-generated output/ names. The Eclipse branch of TJ_NODE pairs a metadata-aware batch loader (Dynamic Image Batch Eclipse) with Eclipse-aware save nodes so the round trip preserves where each image came from. This node is the subsequent step: the thing that saves a result derived from an original - an upscale, a redraw - and files it so you can still tell what it belongs to.

Inputs and outputs

• images - the batch to save.
• filename_suffix - appended to the derived result (default _upscaled), so original.png gets a sibling like original_upscaled.png.
• extension_option - Original (keep whatever the source was), or force png / jpg / webp.
• save_path_opt - an optional explicit save location; leave blank to follow the chain's path logic.

There are no outputs - it's a pure terminal save node.

Installing it

Part of the pack, standard install:

cd ComfyUI/custom_nodes
git clone https://github.com/designloves2/ComfyUI-TJ_NODE

or ComfyUI Manager → ComfyUI-TJ_NODE → restart. No dependencies beyond the pack.

The honest take

This is a niche node inside an already-niche family, and that's okay - you'll only want it if you're doing dataset-style or Eclipse-style work where filenames are the ground truth. If you're just generating and saving to output/, the plain Save Image (Primary-TJ) → Save Image (Suffix-TJ) chain is what you actually want; the Eclipse suffix version adds original-path tracking you don't need. Where it shines: an upscale batch over a folder of source images where you want each result saved right beside its source with a _upscaled suffix and no metadata lost. If that sentence describes your workflow, this is the exact right tool.
