When you're building a new thread with pictures and you put in the picture info,, when you view your post in preview, are you supposed to see the picture yourself?

i have done it, sometimes it shows the image sometimes not.

I think pictures are supposed to show in the preview, but the media center is borked at the moment.

For videos, I came across a thread that said to put the "&" sign at the end of the YouTube video number to see the video in preview. I've tried it and it does work.
