The release fixes some additional cases, when the option "Enable only in forum view" would not be applied.
New option: Enable only in forum view (ver 2.0.0)
The version implements a new option - "Enable only in forum view". If enabled, the thumbnails will be shown only in the forum view (thread list), all other locations will not show any thumbnails (widgets, watched threads, recent posts, etc.). The option is disabled by default.
There is also a fix in the template "altt_thumbnail" which will prevent unneeded SQL queries from executing on forum home page or pages with widgets. Please make sure the template is not outdated in the admin panel, and if it is, make sure to merge it, particularly, to replace $thread.getUserPostCount() && !{$hideSmallAvatar}
with !{$hideSmallAvatar} && $thread.getUserPostCount()
