Image Compare A/B

Shows two images on one panel so differences pop out instead of hiding in a side-by-side. The first frame of each batch is previewed; image_a passes through the output unchanged, so the node can sit in the middle of a graph without breaking anything downstream.

Inputs

• image_a: The baseline batch. Its first frame is preview A, and the whole batch is what the output carries.
• image_b: The comparison batch. Its first frame is preview B.

Panel

Run the workflow once to load the previews, then compare:

• SLIDE (default): move the pointer across the panel. B appears on the left of the seam and A on the right. The outer 6% on either side snaps to a full image. Leaving the preview in any direction settles to the nearest edge, including when you leave through the top or bottom.
• A / B: turn sliding off and lock the selected preview. Clicking the same choice again keeps it locked; choose SLIDE to follow the pointer again. The three choices sit below the image.

The top-centre label reads A or B for a full image and B | A while both are visible, matching their left/right positions. The chosen mode and locked side are stored with the node, including support for modes from older workflows. The resolution sits beneath the panel; differing sizes are labeled individually.

Output

• image_a: The image_a batch, untouched.

Previews are written to ComfyUI's temp folder and vanish with it; nothing is saved to the output folder and no network requests are made.
