Display user picture below content type article
There is a module that comes with the Ctools module called Views Content Panes. Enable that. Also a good idea to enable the Context module, can be fetched here: 
https://www.drupal.org/project/context

Views Content Panes is used to output Views as panel panes. 

Import code for a View that will be a good starting point for your solution is provided at the end of this answer. This view will display the Article's author username and picture.

You may need to edit the "Argument input" setting in the view. 



I set it to use the "From context" option, and the required context of Author.

This has a good chance of working immediately, but we may need to go further into your panels configuration if it doesn't.

After enabling the Views Content Pane module, and importing and saving the view, you will be able to add the newly created pane to your panel.
