That'd be great if it becomes a possibility!

You can solve this by doing this:
1) set the thumbnail source to "First Attachment".
2) go to plugin manager > "Forum Display - Threadbit Display" > find the line containing
$hook_query_fields .= ", MIN(attachment.attachmentid) AS attachmentid";
and append under that line, the following line:
$hook_query_fields .= ", thread.thumbnailurl AS thumbnailurl";

That's all.

I had tried this solution offered and it does work... to a degree.

I found if I set the option to first image in post and then opened and saved a thread with an [IMG] tag already in it, then changed the option back to first attachment. Thumbnails are shown for threads that have an attachment in them or a thread with an [IMG] tag.

Which is exactly what I'm after, but having to change options back 'n' forth and open and save every thread that has an [IMG] tag image in it, isn't ideal obviously!
