Auto generate threads thumbnail on thread list of selected forums.
Tooltip shows full image when hover on thumbnail.

Query: 1
Performance impact: non-notable

I have just started it for 2 hours so it is considered Beta.
Width, height do not currently work as expected because they need some work in css.
Attachment is not available right now but will be added in future.
Since it is beta I recommend to test it first. Don't run on production forum.

Feature requests are welcome but should be within scope.
