ImageAssistedCFGGuider: Samples the conditioning, then adds in the latent image using vector projection onto the CFG. Img2Img works by loading an image like this example image, converting it to latent space with the VAE and then sampling on it with a denoise lower than 1. In this case he also uses the ModelSamplingDiscrete node from the WAS node suite, supposedly for chained loras, however in my tests that node made no difference whatsoever so it can be ignored as well. I know the video uses A1111, but you should be able to recreate everything in Comfy as well. These are examples demonstrating how to do img2img.
