Whenever theres a pic in the forum it comes up as [attachmentid=67344],what does that mean?

It can mean a couple of things:

(1) That the pic has been deleted in the original post. Some of the gorgeous ladies that share their pics are real ninjas. They only leave their pics up for a short while.

Or

(2) That the original pic is on the previous page. You can reply to posts many pages back but the pic that was in that post will only be copied in the replies on the same page.

k thank you
