🦊 RS Image Selector

Batch workflows have an awkward middle: you generate 16 images and you only want to run the good 6 through the expensive second pass. Doing that usually means manually hunting through output folders and rebuilding the batch. 🦊 RS Image Selector (RS Image Selector) sits in the graph, shows you the whole batch in a responsive grid, and lets you click to select the keepers before anything continues. Only the ones you tick pass through to the next node.

How it works

Feed it a batched IMAGE tensor (any node that outputs several images at once), run the queue, and it pauses with a grid of every frame in the batch. Click thumbnails to select or deselect - there are SELECT ALL and DESELECT ALL buttons for the whole batch - then hit ✔️ ACCEPT. The node returns only your selected images as a fresh batched tensor for whatever comes next. ❌ CANCEL aborts the whole run.

A couple of under-the-hood details are worth knowing because they're the difference between this working and silently breaking:

• Heartbeat system. The frontend and backend ping each other during the wait, so ComfyUI won't freeze or drop the session if the browser tab hiccups.
• Auto-cleanup. Selector resources are released when you remove the node or close the workflow, so you don't accumulate zombie sessions in a long-lived server.

Inputs and output

• images - an IMAGE tensor containing the batch you want to filter.
• selected_images - output IMAGE, only the images you ticked, re-batched. Wire it into a KSampler, an upscaler, VAEEncode, or whatever processes the survivors.

There are no other inputs or widgets - this is deliberately a one-job node.

How to install

Part of ComfyUI_RaykoStudio:

cd ComfyUI/custom_nodes
git clone https://github.com/Raykosan/ComfyUI_RaykoStudio.git

Restart ComfyUI, or install via ComfyUI Manager by searching "ComfyUI_RaykoStudio". No model downloads, no extra Python packages beyond the pack's standard set.

Common issues

• It waits forever. Reminder in the README: the generation pauses indefinitely until you click ✔️ ACCEPT, ❌ CANCEL, or close the workflow/page. If you forgot you had it in the graph, that's the "why is nothing happening" answer.
• Nothing selected passes through. If you hit ACCEPT with zero selected, the downstream node gets an empty batch - select at least one first.
• Grid too small to judge. The node auto-sizes based on image count, and you can resize it on canvas; it's a node, not a zooming viewer, so for fine judgment you might still want RS Image Compare.

The honest take: this is a quality-of-life node for a specific pain (curating between passes). If you never run batch-count > 1, it's useless to you. If you do, it beats every alternative of manually tracking which indices were good.
