 # ComfyUI-Image-Selector
-Select one or some of images from a batch
+
+A custom node for (ComfyUI)[https://github.com/comfyanonymous/ComfyUI], which can select one or some of images from a batch.
+
+## Background
+
+ComfyUI dosn't handle batch generation seeds like A1111 WebUI do, so you can't simply increase the generation seed to get the desire image from a batch generation.
+
+So here is a simple node that can select some of the images from a batch and pipe through for further use, such as scaling up or "hires fix".
+
+Or you can use PreviewImage Node to go through all the images, and then rewire SaveImage with ImageSelector to save the one you want.
+
+## Usage
+
+Input: a list of selected indexes, start with 1 (not 0, sorry), seperated by comma.
+
+For example (no surronding quotes):
+
+1. "1": select the first image
+2. "1,3,4,6,7": select the 1st, 3rd, 4th, 6th and 7th image
+
+All indexes that cannot convert to integer or out of bounds will be ignored.
