Avatar on news feed

Hi guys,

Love this plugin guys, I would be lost without it!

Probably really simple but I cannot find the solution anywhere. I do not like the way that the plugin shows a blank avatar image. In fact I would like to either remove the avatar all togethere or show the featured image for each post instead.

The pages in question are:

Sorry about the link drops I just wanted to show I am finding my problem on multiple pages (in fact there is more)
