Hi, I would like to have the ability to add a featured image to my forums and categories (like for posts).
On bbPress we have to add something like that in our function.php file
add_image_size('forum-category-thumbnail', 1080, 320, true);
But I don't know how to make it happen in wpForo...
Could you please tell us what code we need and where to insert it ?
wpForo posts are not WordPress custom post types. You can't use WordPress featured image functions. There is no way to add this in current wpForo version.
