title: Writing 'Image.Image.paste()' to new file
body: <p>I need to paste first picture on second and save new picture as new file. How I can do it? My not-working code in the bottom.</p>
  <pre><code>main_path=&quot;J:/DS_bot/&quot;
  FFP_path=os.path.join(main_path, 'User_image/')
  WFP_path=os.path.join(main_path, 'Results/')
  FFP = os.path.join(FFP_path, filename)
  WFP=os.path.join(WFP_path, filename)
  MFP='J:/DS_bot/Mat/ERd3Wu5UhBc.jpg'
  mat = Image.open(MFP)
  with open(WFP, 'wb') as file:
      Image.Image.paste(mat, resize(FFP))
      file.write(mat)
  </code></pre>
  <p>P.S. If I use <code>mat.show()</code> I can see result,but I can't send it by discord bot and can't save it on my pc. Correct my code and post it near, k?</p>
  <p>P.S. 2 I getting this error: <code>discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: a bytes-like object is required, not 'JpegImageFile'</code></p>
