Pause Image Pixaroma

Upscaling takes a while. A second pass takes a while. Inpainting a big region takes a while. And nothing's worse than committing to the slow part and realizing, four minutes in, that the base image was garbage. Pause Image Pixaroma is a checkpoint you drop into the workflow right before the slow stuff: you wire your image in, run, and the graph stops dead at this node so you can actually look at what you're about to spend GPU time on. Like it? Continue. Don't? Regenerate or fix something upstream. It turns "hope the base is good" into "check the base."

How it works

Flip the toggle to Pause and pressing Run stops here, showing the image while everything downstream waits. The node writes a snapshot to ComfyUI's temp folder, then:

• Continue - only the nodes after the pause run, fed from the exact snapshot you approved. The model, sampler and decode all get skipped, so it's fast, and you upscale precisely the image you saw.
• Regenerate - rolls a new image at this point (it'll differ if your sampler's seed is set to randomize).
• Pass - the toggle's other state; it just runs the whole workflow end to end with no stopping.

One image input (wire any IMAGE source), one image output (the live input in Pause/Pass, or the reloaded snapshot in Continue). That's the whole node.

The gotcha that bites

The snapshot lives in ComfyUI's temp folder, which gets cleared when ComfyUI restarts. So after a restart, the snapshot from before is gone - you need to Run once to pause and create a fresh one before Continue will work. The node tells you when it happens ("snapshot has expired"), but the first time it's mildly alarming. Just run once, then continue.

Where it fits

This is a quality-of-life node for people who iterate: you drop it in front of your upscaler or second pass, and every base image gets a human gate instead of a blind commit. It's also handy mid-branch - pause after a VAE decode to eyeball an intermediate, not just the final. Pair it with Image Compare Pixaroma and you can even leave a before/after sitting next to it. It works in both the classic and the new node interface, and there are Copy / Save to disk / Save to output / Open buttons right on the preview if you want to keep the approved frame.

Install

Part of the Pixaroma pack:

cd ComfyUI/custom_nodes
git clone https://github.com/pixaroma/ComfyUI-Pixaroma

or install via ComfyUI Manager (search Pixaroma), then restart. No extra dependencies. One note from the pack's own changelog: Pause Image keeps the prompt, seed and generation details attached to the image when you Continue, so anything you save downstream carries full metadata - which is exactly what you want if you're feeding results to Prompt Reader later. And the usual Pixaroma rule applies: node looks off after an update, hard-refresh the browser first.
