It's a
long list like this:

They were all in the same folder!? Strange, it is rarely organized like this.
Is this link where you are taking it from, or was it the link being used in the posts?
I guess they're not really in the same directory at imgur's server. It must be a database entry to the actual location, so they can keep the URL as short as possible.
The link I posted is what users actually post on Bitcointalk.
