is this a mature picture or not?
 

I seem to be confused by what constitutes a mature picture. This is from a full page ad in Gear magazine.

Nothing private is shown and I think it's in good taste.

Dude! Come on. It's a naked lady. -biggrin-

Our test is to ask ourselves if this could cause trouble if a coworker or spouse/kids were to see it in passing on someone's computer screen.

Obviously naked women are generally going to fall under this category, and moreover, when posted in a fairly serious thread, as this one was, that type of image can be quite a shocker.

Okay, I understand your test. So, if the thread title had mature on it, the pic would be okay to post?

Yes.

Funny you should ask, actually. If you look a little further down the thread list in this forum, you'll see that weargle was complaining about his thread title being changed. There's more info in there.
