In this release, we have implemented a new option to set the number of posts in the thread to search for an automatic thumbnail. The option is one by default, so product's behavior does not change after installation and only the attachments and images in the first post are considered.
We have also implemented an option to limit the posts parsed to thread starter's posts only. This way only thread starter will be able to set the thumbnail but will be able to do so by just posting another reply containing the image/attachment.
In this version, we have added a new block in Rebuild Caches page allowing to rebuild thread thumbnails. This is required to trigger automatic thumbnails after changes in product's option controlling in which forums automatic thumbnails are enabled/disabled.
We are planning to implement an option to search several posts in the thread for a thumbnail instead of only the first post. The feature will be released in coming days.
This version enhanced the interface for enabling/disabling automatic thumbnails. Now admins can choose to enable/disable automatic thumbnails board-wide, as well as decide in which forums to enable or disable:
Another improvement is lightbox mode for images detected from post text.
The version also fixes several minor bugs reported.
This version implements automatic thumbnail option. If enabled in Admin Panel, all threads will automatically get a thumbnail based on the first attached image in the first post or the first image found in post's text itself.
