Help! Pictures

I've been having trouble inserting pictures in the media center directly into posts. They're in my profile gallery. I've tried (all without the underscore):

[_img]url[_/img] and I get

[_im]url[_/im] and I get

What am I missing??

In the Media Center, under the picture there is three links.

Copy the one under "Embed on ATS''. You just post that code, you don't have to add any other tags.

Thanks! That worked.
