The original code assigns BytesIO(image["bytes"]) to image["image"], but this change directly returns Image.open(BytesIO(image["bytes"])). Ensure that the subsequent fetch_image function is compatible with this change, as it might have been expecting a dictionary with an 'image' key.

return Image.open(BytesIO(image["bytes"]))
