Hi,
The plugin I am referring to is this one:
http://wordpress.org/plugins/bbpress-topic-thumbnails/
The issue is that this one only pulls the thumbnail from the first image in the post. I want a default image to be used for all posts regardless so that the branding of the site remains consistent.
There must be a way to do this through PHP, just I do not know where to start (and I have a limited knowledge of PHP).
Cheers
