title: How to set the image of a Discord embedded message with a variable?
body: <p>So I have my url of the image in a variable. It needs to be in the variable because it changes every time the command is run. Unfortunately, the documentation says that set_image requires a string url, and trying to use a variable throws the 400 error. I then tried doing a simple send_message with the link, but Discord does not download the image into the chat because it is not a string. Does anyone know how to get around this? Thank you!</p>
  
  <pre><code>embed.set_image(url = exampleVariable) #throws error
  </code></pre>
