A basic description on a couple of ways to resize your photos or images so that they will work in ComfyUI.
Stable Diffusion 1.5 is trained on images 512 x 512.
Stable Diffusion XL is trained on images 1024 x 1024.
Most SDXL checkpoints work best with an image size of 1024 x 1024. Image sizes of 768 x 768 and 512 x5 12 are supported, but the results may not be as good. Anything below 512x512 is not recommended
