jobs and experts plugin. avatars not showing

Can't find a solution to avatar images not showing as you can see here

I read a few articles with the same issue however the fixes haven't worked for me. It was suggested to me that this might be a conflict with the 4.5.1 wordpress update but I had the same issue before the update.

I have tried different themes and deactivated plugins to eliminate possible causes. I am hoping somebody can help me with this.
