I see thumbnailed photo attachments in some threads, but I don't see any way to get them when posting... only in-line images.
Thumbnails REALLY help the readability of posts, while those in-line images are really obnoxious.

Am I missing something?

Excellent question. I agree with Patrick.
I have also been searching on how to post JPEG as thumbnails as opposed to in-line attachments ??????
