Blimps have no internal support structure, like a balloon. A "blimp" with internal rigid supports, to help keep its shape, is called a dirigible. An airship specifically built by the "Zeppelin" company is called a Zeppelin (like a truck built by the Ford Motor Company could be called a Ford).

I'm not sure if the OP of this photo used the terms correctly. I suspect not, as I can only find references to Goodyear owning blimps, not dirigibles, and the Zeppelin company does not make blimps.

Edit

Upon doing more research, it turns out I was wrong in the last paragraph. As of 2014, Zeppelin does indeed make non rigid airships, and Goodyear operates one.
