Individual Thread Thumbnail

This was asked in an earlier thread but our site has had more inquiries into the feature. Mainly from another site much like ours that has the feature in their software. Having the first picture attached to the thread's main post auto-cropped and shown in the main forum page. 

I should note that the site I linked to requires at least the 1st image to be attached before a thread may be started. Maybe as an option that would be nice, but I don't see it as necessary. 


Figured this would be a good suggestion for a site upgrade.
