I want to have post count ranks on my forum with the avatars i think i know how to set ranks but how do i make it have like a rank image instead of stars, i put /images/PICTURE.png but still nothing.
You'll have to get a plugin to do this for you or write your own javascript that reads the post count of each user and displays the correct image for the amount in a container somewhere.
My suggestion:
You could also make user groups that automatically upgrade based on post count... give these user groups an usergroup image you want and then presto.. you got what you want!
