Save Image Bridge Simple (Yogurt Nodes)

Save Image Bridge Simple is the Yogurt pack's save node for people who don't want to think about saving. Where the full Bridge variant hands you eight knobs - format, compression, quality, metadata, overwrite - this one gives you four, and two of them you'll never touch.

It does the same core job as its bigger siblings: writes your image to disk, then passes it through so the graph isn't terminated, plus the useful metadata outputs (width, height, batch) and saved_paths - the list of the exact files it wrote. The only real choices you make are:

• images - the IMAGE tensor to save.
• output_dir - leave blank for the ComfyUI output folder.
• filename_prefix - base filename, supports %date:yyyy-MM-dd% tokens and node-value placeholders.
• overwrite - false default means ComfyUI's auto-increment counter appends numbers instead of clobbering.

That's the entire surface. No suffix dropdown, no metadata toggle, no compression slider - it writes PNG, embeds the workflow metadata like a normal save, and moves on.

Why "Simple" exists at all

Honestly? For 90% of the time you reach for a save node, Simple is the right call. The full bridge's extra controls are genuinely useful in their moment, but the default set - PNG, metadata on, auto-numbered filenames - is what you'd pick anyway. The Simple variant also means fewer widgets on the canvas, which matters in big graphs where every node is a strip of sliders. This is the version you drop into a workflow you're sharing with beginners.

The trade-off, naturally, is that there's no format option. If you need .jpg or webp output you have to use the non-Simple bridge (or the Ex variant). That's the one reason to reach past this node.

Install

Same pack, same one-time install as every Yogurt node:

cd ComfyUI/custom_nodes
git clone https://github.com/yogurt7771/ComfyUI-YogurtNodes.git
cd ComfyUI-YogurtNodes
pip install -r requirements.txt

or via ComfyUI Manager → search ComfyUI-YogurtNodes → install → restart. It shows up under Yogurt Nodes → IO as "Save Image Bridge Simple".

Gotchas

Keep the two family rules in mind: non-output concerns aside, this one is an output node, so it shows in the frontend gallery normally. And overwrite=false is the default - re-running a workflow stacks numbered files. If you want a fixed filename per run, flip overwrite on. The saved_paths output is your friend when you need to know exactly where something landed, since the auto-numbered names are otherwise a mild guessing game.
