Find first bug in the mimetypes.guess_extension(mime_type)

sometime, if the type of my image is image/webp , this code will work incorrectly !
it will return none😂

so that i change the code like this

image_format = (
    ".webp"
    if mime_type == "image/webp"
    else mimetypes.guess_extension(mime_type) or ".png"
)

The second bug is that when I download an image using ios safari, it doesn't recognize my image type, so it saves it as a text file and can't be saved properly. I'm not sure if this is a situation that everyone uses

Thanks the author for his efforts
