Text-Guided Image-to-Image Generation
The StableDiffusionImg2ImgPipeline lets you pass a text prompt and an initial image to condition the generation of new images.

init_image = Image.open(BytesIO(response.content)).convert("RGB")
init_image.thumbnail((768, 768))
prompt = "A fantasy landscape, trending on artstation"
images = pipe(prompt=prompt, image=init_image, strength=0.75, guidance_scale=7.5).images
images[0].save("fantasy_landscape.png")You can also run this example on colab
