Can anyone share information on how/where I might be able to adjust the forum attachment image thumb size to a more viewable size? Default size is a bit too small for my preference. I searched for possible answers in these forums but only found possibles for earlier version of PHP-F. I'm on v9.03.110.
Paste it into your theme styles.css. Just set width and height as you like (If you also have styles.min.css, delete this file and keep only styles.css)
