This workflow is just a simple upscaler to upscale your images in batch, either made with Stable Diffusion, photo's made on your holidays or just a whole bunch you'd like to have a bit bigger in size. Just copy the path of the folder of your images into "Load Image Batch From Directory" and you'll do the same thing with the "Save Images" when clicking on the "filename_prefix".
Everything else is explaned in an attached note in the workflow.
