How to fetch the ED UserAvatar to show inside a custom module?

Hi Guys,
I want (need!) to show the user avatar inside a module position like Joomshaper did (please see attached Screen).

I got all, the dropdown, the username fetched, but now i just need the image from easydiscuss.
Can you help with script?
I´m using Sourcerer, so PHP would be no problem...

thanks for your help.
