I want tomake a command that basically takes an image that the user sent. I'm using the pillow library.
@bot.command(pass_context=True)
async def task(ctx):
    userimg = attachment.url[0].url
    print(userimg.size)
    background = Image.open("task_failed.jpg")
    print(background.size)
    size = (640,2030)
    background = background.resize(size,Image.ANTIALIAS)
    background.paste(userimg, (0, 0), userimg)
    background.save('memetask',"PNG")
How am I supposed to complete this?
