Boyo Load Image Batch (Input Folder)

Sometimes you don't want all the images in a folder at once - you want one at a time, in sequence, with your batch loop advancing through them. That's Boyo Load Image Batch. It loads a single image from a subfolder of ComfyUI's input/ directory and, in incremental mode, advances to the next file each time it executes. Think of it as a per-iteration image iterator for batch processing, and the reason you'd pick it over a plain Load Image is the subfolder dropdown: no typing paths, which keeps things reliable on Linux and cloud boxes.

It's explicitly modeled on WAS's Load Image Batch, so if you've used that, this is a familiar shape with a Boyo skin.

The inputs that matter

• mode - single_image (load by explicit index), incremental_image (advance through the folder each execution), or random (seeded pick).
• index - which file to load in single_image mode (0-based, by sorted order).
• seed - used for the random mode, so you can reproduce a given pick.
• subfolder - dropdown of input subfolders. Drop your files in ComfyUI/input/<subfolder>/ and it shows up here.
• pattern - glob filter, default *. *.png if you only want PNGs.
• allow_RGBA_output - keep the alpha channel or flatten to RGB.
• label - just a batch name tag, mostly cosmetic.

Optional filename_text_extension controls whether the filename output includes the extension.

Outputs: image (the loaded frame) and filename_text (the matched filename, handy for wiring into a save node or metadata).

Install

Part of Boyonodes. ComfyUI Manager → search "Boyonodes", or:

cd ComfyUI/custom_nodes
git clone https://github.com/DragonDiffusionbyBoyo/Boyonodes

Restart. No extra pip packages.

How incremental actually works

Here's the clever bit: in incremental_image and random modes the node's IS_CHANGED returns NaN, which forces ComfyUI to re-execute it every queue run instead of caching the result. That's what makes it step forward through the folder with a batch loop instead of returning the same image forever. If you ever feel like it's "stuck," check the mode - single_image is deliberately static. Also note it only matches the pattern in the chosen subfolder; if you get a silent (None, "") back, the folder or pattern is wrong.
