XF 1.4 Hide avatars in threads for users with default avatars only

[Gladius]

I've got a rather simple thing that I want to do that was easy enough in vB, but at a glance not so in XF. I want to hide (disable, remove) the display of avatars of the users with default m/f/? avatars inside threads. Is there an easy way to do it?

I want to do it too.

It would likely be possible by using a conditional statement to check for the existence of an avatar or gravatar and only displaying the avatar block if it returns true.

These guides should help:

Could it be done changing the default avatars to a 1x1 pixel clear image?
