I am not a supporter, but I see that other Full Members have this capability. Here's a thread I made asking about it in Adult...with examples...

SternFanNetwork

attachments are only available to supporters.

thread thumbnails are generated by the first uploaded attachment. if you can't upload you can't get the thumb.

as for the paperclip in the advanced message editor, that is a list of the attachments on a post. if don't have anything attached, you don't see the clip.

as for other supporters having thread thumbs while you don't, I made them. I went into some threads and uploaded 1 pic to each thread so you guys could see what thread thumbnails look like.


now there is a paperclip on the forum display page that you will see. any thread with uploaded attrachments gets one. if you click on it, you'll get a popup with a list of all the attachments in a thread.
