XF 1.4 Display short text+image instead of avatar in threads


Well-known member
I need to recreate our 30+ "user ranks" from vB but it seems that I can't use the User Title Ladder for this as it doesn't support HTML... I need two short lines of text and an image below them to replace the avatar for those users who have no avatar set. The text and image displayed depends on the number of posts the user has.

What would be the easiest way to achieve this?
