In the faq section of the documentation there is an example of how to do this. You will find this here.

Also, in your command called image you are missing the ctx parameter that commands require. From the ctx parameter you can get the message and the channel because at the moment I am not sure where you are getting the channel in line 3 of the image command from and also the message in line 3 of the ping command.

MhmCats answered the question, but I have noticed you have time.sleep and requests in your imports. This may or may not be blocking depending on how you're using them, but generally, they are and you should avoid them.
