How to change default_teamblog.png

After updating to EasyBlog 5 the default teamblog icon/avatar is displaying. I would like to change this to display the teamblog avatars or to display no avatar.

Here is the one being displayed:

You can see an example here of the avatar appearing next to the Author's avatar:

Actually you will see that the blogs that we posted since updating to EasyBlog5 are NOT displaying any teamblog avatar and that is fine by us.

All of the posts originally generated in EasyBlog 3 are displaying.

On the page above you will see that the blog post titled "Can Low-Carb Diets Impair Brain Function?" does not show the teamblog avatar. I am happy with that.

Maybe just help us to remove it from the other older blogs???

Thanks, Sean
